Hi!

I've got a "Bull Express5800/Series" (dual P3) with a DAC1164 RAID
controller. The mainboard is ServerWorks based and however, 2.4.2-pre3
fails to find the RAID controller. I think there's a problem at
scanning PCI busses behind PCI bridges. Here's the PCI bus layout as
2.4.0-test10 recognizes it:

-+-[01]-+-04.0 Adaptec 7899P
 | +-04.1 Adaptec 7899P
 | \-0a.0-[02]--+-08.0 Digital Equipment Corporation: Unknown device 1065
 | \-09.0 Mylex Corporation eXtremeRAID support Device
 \-[00]-+-00.0 Relience Computer CNB20HE
        +-00.1 Relience Computer CNB20HE
        +-02.0 ATI Technologies Inc 3D Rage IIC 215IIC [Mach64 GT IIC]
        +-03.0 Intel Corporation 82557 [Ethernet Pro 100]
        +-06.0 Intel Corporation 82557 [Ethernet Pro 100]
        +-07.0 Intel Corporation 82557 [Ethernet Pro 100]
        +-0f.0 Relience Computer: Unknown device 0200
        \-0f.1 Relience Computer: Unknown device 0211

Here's log output from both 2.4.0-test10 (successfully booting) and
2.4.2-pre3 (no success due to missing root fs):

Can you give me some advice on how to hack those PCI bridges?
