The 5530 isn't matched by the PCI router code so we fall back to the PCI
BIOS32 services which do know what they are doing.

I have the 5520 data sheet. For IRQ routing the 5520 and 5530 are
identical according to the docs and code according to the docs doens't
generally work ..
If you need to set these for LinuxBIOS then perhaps matching and setting
it up only if LinuxBIOS is present would be the better choice ?
