This might be related to these earlier reports on the LKML
On a Thinkpad Dock II, there is a PCI video card system which is not visible on my Linux system. (I have tested the card on an old desktop and it is detected.)
I am attaching the output of dmesg, lspci -vvv and acpidump. Notice that in the second of these I can see the docking station itself; like in the second problem report quoted above, the card itself doesn't show up in lspci, though.
Thanks for any time you can devote to this,
Forgot to mention: based on information online, I have tried booting with acpi=off, pci=assign-busses, pci=routeirq, pci=noacpi and pci=nobios to no avail.

[[Ugh, I fat-fingered the [Bug 15436] in the subject, so the last one
went to the wrong bugzilla.]]
[Updating this thread with the bugzilla pointer and my current theory]
I first thought this was an ACPI or dock problem, but I now think
this is a PCI issue after all, since the machine was booted in the
dock and no dock/undock events are involved.
From this lspci output:
00:1e.0 PCI bridge: Intel Corporation 82801 Mobile PCI Bridge (rev 81)

It looks like the dock PCI slot should appear as 0b:00 (as it does in the
report at http://lkml.indiana.edu/hypermail/linux/kernel/0607.0/1409.html).
We do see the CardBus bridges in the dock. The fact that we don't see the
video card, which should be on the same bus, makes me suspect that the
dock's PCI slot is bad.
