Same here (with 2.4.16):

PCI: PCI BIOS revision 2.10 entry at 0xfdb91, last bus=0
PCI: Using configuration type 1
PCI: Probing PCI hardware
PCI: Error 89 when fetching IRQ routing table.

If I boot without pci=biosirq, the systems fails to recognize some
interrupt (I think it was 14) and tells me to use pci=biosirq. The
system _seems_ to be running fine, though (with or without biosirq
option)
