First, you have to build a new linuxbios image using buildrom.  That's
described here:
http://wiki.laptop.org/go/Building_LinuxBIOS
You definitely want to use revision 2432 or newer (that's what I used).
Edit Config.mk, setting LINUXBIOS_VER to that.  LinuxBios doesn't
currently build under Fedora, but it builds just fine under Ubuntu
(dapper).

If you'd like, I can just send you the rom image that I used.

Once you've flashed the rom image onto your board or PLCC chip
(http://wiki.laptop.org/go/Flashing_LinuxBIOS), the build86 Fedora image
should work fairly well.  Make sure the various kernel modules are
loaded (psmouse, evdev), and you should be okay.  By default, xorg.conf
will use /dev/input/mice.  This should work okay w/ the touchpad, but
isn't really desired in the long run (the evdev driver is what we want).
However, that requires upgrading to xorg 7.2, and doesn't seem to work
all that well yet (at least not for me).
