it's not hard to bring up a new kernel with linuxbios. the hard part is that
the hardware is in a weird state, having not ran any of the proprietary bios
(8086 emulation, don't forget) code to initialize it.
things like vga, sometimes even memory, will be in a complete disarray,
nevermind the fact that with linuxbios 9load starts looking for a kernel
before even the hard drive has spun (that's how fast things are).
linux deals well with those things because it doesn't trust the hardware,
freebsd is also fine. plan9 on the other hand didn't know what a $PIR
table is before R4 (i didn't either, but that's a different issue altogether :)...
admittedly the 9fans crowd isn't too interested in this stuff but it's
something Ron cares for to a great extent.
