[LinuxBIOS] Desktop computer use?

I'm curious about a few things about LinuxBIOS. First
off, is LinuxBIOS usable (or intended to be) in a
standard desktop environment, or aimed solely at
embedded/cluster application? If the answer to that
question is the latter, ignore the rest of this post.

I'm looking to use linuxbios on an intel bi440zx, a P3
mobo with a 440zx chipset. I'm wondering if anyone has
worked on support for this motherboard, or even this
chipset, or if the code for the 440BX chipset works as
a drop-in replacement. 

Info as requested in FAQ:
CPU: I'm currently using this mobo with a 466MHz
Celeron (Mendocino core) due to BIOS limitations. The
chipset (440zx) supports 100MHz FSB, and I have a P3
1.0GHz (133*7.5), would it be possible to use this
chip with linuxbios and run it at 750MHz (100*7.5)?
The current BIOS doesn't allow this. This is one of my
main reasons for looking at linuxbios, the other being
that it will be a fileserver, and the faster the boot
time the better.

Other: 40gb hard drive and ATAPI cdrom connected to
built-in IDE, and possibly a PCI IDE controller with a
250GB hard drive (this wouldn't matter at boot time,
only after the kernel loads). Computer will most
likely be controlled mainly through ssh once it's
completely set up. ISA support is not needed, nor is
the built-in ES1371 audio controller.

If either the Rage or the Voodoo work, I'm happy, but
I have no need for both, I just installed had to flash
the voodoo's bios to get it working, and haven't
removed the rage yet.

Super I/O: I think this is the right chip: SMSC

BIOS info: Intel E28F200 2Mbit Flash bios (info in
mobo docs) 

Online documentation:
Southbridge (although this appears to be already

Thanks for any help you can offer in giving this old
system a new life ;)
