When running LinuxBIOS it isn't an issue, as LinuxBIOS doesn't
write to the flash chip during bootup.

You can squeeze LinuxBIOS and etherboot into 64kB if you have to.
It is much nicer to get a slightly larger chip and put two copies
of LinuxBIOS in it.  Of course support for that hasn't been implemented
on the K7SEM :(  This allows you to develop and play with LinuxBIOS without
needing to use a special flash burner.
