Well, I hope someone will speak up, because I can offer only some general
remarks, having no on-hands experience with CompactFlash:

* if possible, use IDE flash - it's easiest to support on various OS-es.

* then, try to use M-Systems' DiskOnChip - there is a driver for it. 

* if not, all devices which are accessible via BIOS INT13h will work as
long as you only want to boot from them - once you start the kernel, they
are inaccessible. Once upon a time some people (msmith) were trying to
write a disk driver using BIOS INT13h and VM86, and failed (AFAIK they
still have nightmares from that experience... ;-)

* and finally, I have no idea what is the interface between the
CompactFlash and the rest of the h/w and s/w.
