Ok.. New note:

Don't run the bootmenu installer from SD (at least for me).

In the cloned SD boot the MMC cards are backwards from both flash and debian..

meaning that /dev/mmcblk1p2 is my external in SD Diablo, but in Flash and for the bootmenu it is /dev/mmcblk0p2 - do not know why. So when I installed the bootmenu from SD I would select to boot to Deblet and immediately get "boot failed, booting from flash"

Other note.. the Bootmenu installer only makes an entry for deblet and flash =-(.. After loading that i lost the entry for my boot to SD.. I think you should add Penguinbait-like capability in searching for available ext2/3 partitions and prompting the user (Which Partitions would you like added to the bootmenu?) Including maybe a name?? Otherwise if it's automatic just call it "unknown" ... or something lol.

Now.. the installer DID work.. it's just.. my SD cards are flopped and that was the way the bootmenu wrote so I had to reload penguinbait's anyway..
