Do you have a working Config.lb I could look at?

Ah okay, under what circumstances does the fallback run?

I cut & pasted this program:
  http://linuxbios.org/pipermail/linuxbios/2004-March/007257.html
and it seems to have flashed without trouble (both the program itself
and flashrom said the new BIOS was verified, hooray).

Despite my earlier test I'm hesitant to reboot as I've no backstop in
case I brick it - will review my options for recover, possibly purchase
a backup chip and pop back in a few days :)
