Fancy Kernel r42

- init.superuser.rc: fix root issues on some ROMs (I simply forgot to add two command lines last time when updating the RAMdisk)
- fancyinit2 / bigmemcheck: still disable 1080p recording with BIGMEM-enabled kernels, BUT also put an init.d script in place, which will automatically re-add the 1080p modes when another kernel is installed
