New Revision: 4080

Modified:
   trunk/coreboot-v2/src/mainboard/emulation/qemu-x86/mainboard.c
Log:
This is a bit of an emergency fix for qemu. Ethernet routing has not been 
working. Given all the limitations of PIRQ routing we keep it simple
and just set the IRQ directly. Most BIOSes are doing setup this way anyways, 
since there are so many errors in PIRQ tables.
