Strange. I use kernel 188.8.131.52 (from fedora fc7) and I don't need
noapic with proprietary bios, but after coreboot, it complains that
'8254 timer not connected to IO-APIC' and then goes into panic, saying
that 'IO-APIC + timer doesn't work' with suggestion to use the 'noapic'
parameter. With the 'noapic' it doesn't go into panic there, but other
troubles occur (with the SATA irq).
What VGA do you use? (if any...) Did you experience any trouble there?
What about the 'CONFIG_VGA_ROM_RUN' option? No chance for me as long as
this rom signature is wrong... or?

Who can tell me? Anyone?
What files to modify to get the mappings the same -- without breaking
