[PATCH] Fix incorrect Asus k7m irq router detection This patch: http://marc.theaimsgroup.com/?l=bk-commits-head&m=111955644929114&w=2 uncovered a k7m bios bug, where the VT82C686A router is reported as being "586-compatible". The two chips have different pirq mapping, so this leads to "irq routing conflict" on many pci devices. The suggested fix was discussed with Aleksey Gorelov, who helped me to identify the problem as a probable bios bug.
