FWIW, below is a digest of the process to create a SD card running CM10.0 builds by XDA Developer Succulent which is posted at his blog http://iamafanof.wordpress.com and which I have used to build a CM10.0 SD card for my 16GB Nook Tablet:

Download the pair of files cm-10-yyyymmdd-UNOFFICIAL-acclaim.zip and cm-10-yyyymmdd-UNOFFICIAL-acclaim_sd_hd.zip from http://iamafanof.wordpress.com/2012/11/03/cm10-0-jelly-bean-for-nook-tablet-uploading/, and SD_Boot.zip from http://iamafanof.wordpress.com/2012/11/11/how-to-guide-bootable-cm7cm9cm10-sdcard-for-nook-tablet/.

Download gapps-jb-20121011-signed.zip from http://goo.im/gapps/gapps-jb-20121011-signed.zip.

Using a disk partition tool (such as MiniTool Partition Wizard Home Edition) create 4 partitions: boot (Primary, FAT32), system (Primary, Ext4), data (Primary, Ext4), and sdcard (Primary, FAT32). Set the partition ID type for the boot partition to 0x0C FAT32 LBA and set its Active flag (otherwise the SDcard will not be bootable). Once this is done, the boot partition should appear as a (read/write accessible) drive under Windows. (Note that you can adjust the suggested sizes of the partitions upward to fill up the entire SDcard; FWIW the sizes I use on my 8GB card for the 4 partitions are, respectively: 0.5GB/0.5GB/2GB/[remainder of SDcard]).

Copy to the boot partition of the SD card the following files from cm-10-yyyymmdd-UNOFFICIAL-acclaim_sd_hd.zip: boot.img (in folder p2), flashing_boot.img, MLO, recovery.img, u-boot.bin.

Modify the zip files using drag and drop with winrar/winzip (do not extract and repack the zip files):

Replace updater-script in folder META-INF\com\google\android of cm-10-yyyymmdd-UNOFFICIAL-acclaim.zip with the updater-script from in folder p2 of cm-10-yyyymmdd-UNOFFICIAL-acclaim_sd_hd.zip.

Replace vold.fstab in folder system/etc of cm-10-yyyymmdd-UNOFFICIAL-acclaim.zip with the vold.fstab from folder CM10_Jelly_Bean\1_os of SD_Boot.zip.

Replace updater-script in folder META-INF\com\google\android of gapps-jb-20121011-signed.zip with the updater-script in folder CM10_Jelly_Bean\p2\gapps of SD_Boot.zip.

Copy to the boot partition of the SD card cm-10-yyyymmdd-UNOFFICIAL-acclaim.zip and gapps-jb-20121011-signed.zip (that get modified with the replacement updater-scripts and vold.fstab files in the above steps).

Put the SD card into the NT, and boot from its power off by inserting a powered USB cable. Press and hold the N button as soon as CyanoBoot comes up to get the boot menu to display.

Select SDC Recovery.

[Optional but recommended step, in case you accidentally forget to replace the updater-script file(s)] Select Backup to backup your current NT config (/boot, /recovery, /system, and /data).

Select "Install zip from SD card" and install the modified cm-10-yyyymmdd-UNOFFICIAL-acclaim.zip file.

Select "Install zip from SD card" and install the modified gapps-jb-20121011-signed.zip file.

Select "Power off" to turn off the NT.

Boot the NT from its power off by inserting a powered USB cable; after about a minute you should see boot animation lasting for a few minutes followed by initial wifi network and google account setup process, after which your CM10 on SD is ready for use.

A few additional points worth noting:

If you plan to backup your NT current ROM config then add to the boot partition size at least 600MB for each backup (to save space you can copy/archive backup data folders to your PC and remove their copy from the boot partition).

Generally the lower rating (and also cheaper) class 4 SD cards are more suitable for running a ROM than the higher classes 6 and 10 cards (since the latter are optimized for large & sequential block read/write at the expense of random read/write). So if you happen to use a class 10 or 6 card and your apps frequently crash or freeze, consider switching to a lower class SD card.
