Sorry, I worded the above paragraph far too strongly.  I meant to say
that booting a COTS BIOS & Linux and running util/getpir and
util/mptable can be very useful in LinuxBIOS v2, but hand editing the
results may be required.  It would be nice, if util/getpir and
util/mptable could be modified so hand editing the resultant
irq_table.c and mptable.c would not be needed.  This may not be very
useful for experienced LinuxBIOS developers, but can save a lot of
porting time for people who don't have as much LinuxBIOS or other BIOS
experience.

Sincerely,

ah! tell me how it needs to change. I just used getpir recently and did no 
hand editing.

If there are several peer root bus, the irq_table.c must be modified maually.

Please refer to src/mainboard/tyan/s2895/irq_table.c

Also, on AMD K8 CPUs it needs to be modified due to the difference in
breadth-first vs depth-first bus enumeration, resulting in different bus
numbers.

ah, somebody fix it please :-)

No, the irq table can be produced dynmaically as mptable.c

the developer must change irqtable.c mptable.c manually to make it dynamically.
