I can't see why not. For that matter, I can't imagine
it would be too hard to write the necessary flash
support to get LinuxBIOS working.

It does puzzle me, though, that the kernel seems to
get a lot of data from CFE rather than using the
probes it already has. Whether it's a built-in BIOS
(as on the PC), ACPI, CFE, or some other external
table of what is present, the one thing experience has
taught is that these tables cannot (and should not) be
trusted. Kernel discovery, although unsafe for some
hardware*, generally produces more accurate and
reliable results.

*Of course, that's a killer. There is an unfortunately
large amount of hardware in the world that cannot be
used safely in conjunction with probes. Other hardware
will respond incorrectly, screw up the machine, play
all your MP3's backwards, ...
