Okay, so how about this then ?

      pci, x86: add workaround for bug in ASUS A7V600 BIOS (rev 1005) · 75b19b79
      由 Bertram Felgenhauer 提交于 
      This BIOS claims the VIA 8237 south bridge to be compatible with VIA 586,
which it is not.

Without this patch, I get the following warning while booting,
among others,

Now that's an VIA 8237 chip, so pirq_via586_get shouldn't be called
at all; adding this workaround to via_router_probe() fixes the
problem for me.

Amazingly I have a 2.6.23.8 kernel that somehow works fine ... I'll
never understand why.

      PCI: Correct last two HP entries in the bfsort whitelist · a1676072
      由 Tony Camuso 提交于 
      Greetings.

There is a code flaw in the bfsort whitelist, where there are redundant
entries for the same two HP systems, DL385 G2 and DL585 G2. This patch
replaces those redundant entries with the correct ones. The correct
entries are for large-volume systems, the DL360 and DL380.

-----------------------------------------------------------------------

commit ec69f0374c3b0ad7ea991b0e9ac00377acfe5b1a
Author: Tony Camuso <tony.camuso@hp.com>
Date:   Wed May 14 07:09:28 2008 -0400

     Replace Redundant Whitelist Entries with the Correct Ones

     The ProLiant DL585 G2 and the DL585 G2 are entered reundantly
     in the dmi_system_id table. What should have been there are the
     DL360 and DL380. This patch simply replaces the redundant
     entries with the correct entries.
