Dear Chris,
although I'm not in the developer crew, please go ahead.
I just tried the compiled stuff ...

it is not possible to chainload into the CD, when coming from
a floppy, GRUB does not recognize the CDROM :-(
but that might also be BIOS dependent ...
but that might be a smaller patch, but not on my side, I'm not
a C guru.
But, as far as I understand Leonid's posting, it should work,
when having it on a CD in no-emulation mode.
See also: http://www.nu2.nu/bootablecd/ about the no-emulation
mode although this page is quite heave directed to Redmont and
other commercial stuff.
PS: Please keep me informed about successes/failures.
regards
