Can you do an "lspci -vvn"? I'm looking at quirk_via_irqpic() in
2.6.9, which is what printed this:

PCI: Via IRQ fixup for 0000:00:07.2, from 9 to 10
PCI: Via IRQ fixup for 0000:00:07.3, from 9 to 10

but it looks like it should only run for PCI_DEVICE_ID_VIA_82C586_2,
PCI_DEVICE_ID_VIA_82C686_5, and PCI_DEVICE_ID_VIA_82C686_6.

You have:

0000:00:07.0 ISA bridge: VIA Technologies, Inc. VT82C686 [Apollo Super South] (rev 40)
0000:00:07.1 IDE interface: VIA Technologies, Inc. VT82C586A/B/VT82C686/A/B/VT8233/A/C/VT8235 PIPC Bus Master IDE (rev 06)
0000:00:07.2 USB Controller: VIA Technologies, Inc. USB (rev 1a) (prog-if 00 [UHCI])
0000:00:07.3 USB Controller: VIA Technologies, Inc. USB (rev 1a) (prog-if 00 [UHCI])

and we apparently ran the quirk for 07.2 and 07.3. I wouldn't
have thought those would have one of the above device IDs. The
"lspci -vvn" should tell us for sure.

2.6.11 removed that quirk and runs quirk_via_bridge() for
all VIA devices, but only sets via_interrupt_line_quirk if
(pdev->devfn == 0), which you don't have. So that's why
my patch didn't do anything.

Also two more questions:

1. What is VIA fixup? Is it some hardware bug? Or BIOS problem? Why is it
needed? On what hardware / software it is needed?

I really don't know much about the VIA fixup. I just noticed
that we seem to be doing it slightly differently in 2.6.11 than
we did in 2.6.9, and thought maybe it was related to your problem.
Here's a changeset that has a couple pointers:

http://linux.bkbits.net:8080/linux-2.5/cset%4041cb9d48DRV4TYe77gvstTawuZFYyQ

2. Why this patch shrinked bzImage that much:

-rw-r--r-- 1 root root 1828186 mar 11 23:33 vmlinuz-2.6.11-cko1
-rw-r--r-- 1 root root 1828355 mar 2 20:48 vmlinuz-2.6.11-cko1.old

I have no idea about this. But it's only a couple hundred bytes.

So here's another patch to try (revert the first one, then apply this).
