As far as I can tell from the lspci, the only devices behind the docking 
bridge are

	0a:01.0 IDE interface: Silicon Image, Inc. PCI0648 (rev 01) (prog-if 8f [Master SecP SecO PriP PriO])
	0a:02.0 CardBus bridge: Texas Instruments PCI1420 PC card Cardbus Controller
	0a:02.1 CardBus bridge: Texas Instruments PCI1420 PC card Cardbus Controller

and they all like they should work. Apparently exactly because the docking 
bridge is this one:

	00:04.0 PCI bridge: Texas Instruments PCI2032 PCI Docking Bridge (prog-if 01 [Subtractive decode])

and that bridge itself is already transparent, so the fact that we 
couldn't allocate any explicit windows for it really seems like it 
shouldn't matter.

So those are the docking bridge resources, but if I understood correctly, 
what you have issues with is that you want a graphics card in the dock to 
work - and I can't even see it in the lspci output. I see this one:

	01:00.0 VGA compatible controller: ATI Technologies Inc Rage Mobility M3 AGP 2x (rev 02) (prog-if 00 [VGA controller])

but that is the built-in laptop graphics. You say that you have another 
graphics card that used to be at 02:00.0, but it's not showing up at ALL, 
so this is more than some random resource allocation issue - this is a 
device not even even being enumerated. That's very different - it implies 
that some bridge isn't turned on at all.

Can you do the dmesg and lspci for the kernel where this works?
