So, from 1000 miles away...

Doesn't Debian's initramfs bring up udev and let you use the
/dev/disk/by-*/ symlinks in crypttab?  That's a *LOT* better way to find
this drive (in your case, by-id might work, and by-uuid will almost
definitely work, assuming a new-enough udev that can find the UUID of a
LUKS volume).  Maybe poke around in /dev/disk when you're at the busybox
prompt, and see what you can find.

(If it doesn't bring up udev and let you use those symlinks, then ...
why not?  :-P  Not a question for you obviously, but more for the Debian
maintainers.)

Anyway, then you don't care which sd* name is given to this device,
since you're using an explicitly-guaranteed-stable name for it.
