Do we have enough info to route the irq in the bridge chip in linuxbios, 
assuming the kernel doesn't know about epia-m?  If so, you can set the 
upper bit(s) in the link byte in the irq table and linux will use it as 
pre-routed.  No kernel patch needed.  See v1 
/src/mainboard/stpc/consumer2; I did this for the stpc.
