[Motorola Droid X2] Igtenio:
I've tested some more, and while I can't get both the internal storage and the SD Card to show up at the same time and work correctly, I've gotten it so that the SD Card shows up as...an SD Card. While internal storage is inaccessable, this works correctly in settings, and it shows as an SD Card. Until someone can get a set up going that correctly mounts everything, I think this's the best we're gonna get.

vold.fstab to mount sdcard to /mnt/sdcard, but internal memory is inaccessable;

Here you go. The only difference is the mount points; the one posted earlier in this thread swaps /mnt/sdcard-ext and /mnt/sdcard-ext.
