$ If someone were willing to help me out with this, I'd really appreciate
$ it. Unfortunately, I think the interrupt routing is going to be somewhat
$ screwed on my Libretto here until I can use the PCIBIOS to configure it.

My note PC has PIR table, but your machine does not have PIR table.

So I try to call get_intr_routing() from pcibios_pir_init() with next patch.
kernel failed boot with My note PC(Toshiba Satellite 2550X).
Message is below(copy by hand):

 uvm_fault(0xc03b2c20, 0x6000, 0, 3) -> e
 kernel: page fault trap, code = 0
 Stopped in pid 0(swapper) at 0xc0489e79: movw	%dx, 0x14(%bp)

I think that get_intr_routing() is not tested well,
because most Note PC has PIR table.

I don't know what non-Toshiba note PC happened with next patch.
Any suggestion??

# Sorry,My english is poor! but I'm interesting this problem.

Regards!
