as PCI->HOST bridges on my (440BX) box.
My change is to remove the test at the beginning entirely, letting the
switch on the device ID happen first. If the device ID is unknown, then
(in the default case) check for the generic PCIS_BRIDGE_HOST tag. This
should allow wierd cases (eg: wpaul's IMS VL bridge) to work by using the
id override. This strategy is more in line with the other PCI match
methods we use elsewhere,
I only have a limited testbed, but having my USB etc devices detected as
PCI->HOST bridges doesn't look good.
