Not likely to help. And certainly not Steve's problem. For him, moving
the *BIOS* reboot up would help.

I do think that to fix Steve's issue, we should probably remove the
PCI from the list of defaults again. So I agree with Matthew in that
sense, I'm just arguing that real production hardware still (sadly)
very much does need it.
