[PATCH] Fix incorrect Asus k7m irq router detection Here is 2.4 version of a patch submitted earlier for 2.6 by Giancarlo Formicuccia. 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.
