Not yet :( but that's coming :)
I'm doing it the Grub Legacy way of having a "stage 1" sp
an
iso9660 already there, but how can I tell grub2 to actually mount the
CD-ROM drive as an iso9660 filesystem?
Thanks!

image, load it in memory and boot it, the boot image itself wouldn't
work until we provided the Int 13h interface.
Just my opinion...

I vote for it.
That's what I plan on doing... I want to write a module that for now
just allows me to test various int 13h calls, look at their return
values and get a general idea of how things work.
Thanks for the idea Vesa!

It prints debug messages depending on a
variable. For example, use "set debug=all" on the GRUB prompt. I
think it is easier for you to start playing with grub-emu to
understand how things in general work. Although it will be useless to
you when you start working on your project.

You should probably have a look at http://www.linuxbios.org/FILO maybe
you can salvage something. FILO supports booting from ElTorito bootable
CD media, uses 32-bit mode, and it is free of bios calls. Unfortunately
its x86 only, although some work has been done to get it running on PPC.
