Sorry, I suppose I didn't explain all the steps.
Ultimately, I booted into konppix (32bit) and changed the automatic entry in
cypttab and fstab to noauto ( this normally asks for a password at startup so
encrypted disks can be mounted ). That allowed the boot process to continue
automatically. After crossing everything and waiting for all the fscks to
finish I got a login screen.
Then I installed refind ( a EFI bootloader alternative to Grub2) which doesn't
cause the boot process to be hidden.
The original problem I was trying to fix still isn't fixed - refind doesn't
remove the warning I get in the log, but it's not the reason I posted.

Yes - the keyboard, mouse, network (and probably others) stopped working when
a 64bit kernel is running.

It's always been in text mode as far as I can remember

Yes - some HDD light flashing but as it's on a SSD it never flashes for very
long anyway. After disabling the automatic crypt disk mounting it started
performing checks on the harddrives and eventually started X
