Hi,

while playing with 2.6.16-git kernel from today, I've found out following 
message in dmesg:

PCI: Bus #04 (-#07) is hidden behind transparent bridge #02 (-#04) 
(try 'pci=assign-busses')

My notebook is HP nc6120 (Pent-M, ICH6). So i've rebooted with said parameter 
and dmesg changed a bit, finding new "resources" (not sure what's the proper 
terminology :)

Here's a diff before and after adding the parameter (I'm also attaching full 
dmesg output).
