vt8601 support is already present in linuxbios, and I'm currently
working on vt82c686 (which should work, but I haven't had a chance to
test it yet). There are two variants of the 82c686, the a and the b. Can
you either check the manual to find out which one of these it is, or
reply with "lspci -n"? Then, beyond that, it's the code for the actual
motherboard, which usually isn't too hard.

Find an electronics shop that can do sodiering work, and get them to
install a socket on one of the motherboards, and then get a couple extra
bios chips (mouser.com I've had very good luck with). There's a chance
that your flash could work perfectly the first time, but if it doesn't,
you're out a motherboard, there is no reflash.
