( for 2.6.19, and i think it would be good for -stable too... )
[PATCH] fix via586 irq routing for pirq 5
fix interrput routing for via 586 bridges. pirq can be 5 which needs to be mapped to INTD. but currently the access functions can handle only pirq 1-4. this is similar to the other via chipsets where pirq 4 and 5 are both mapped to INTD. fixes bugzilla #7490
