Please note that my patch does only change those occurences where

pci_write_config32(dev, 0x7C, 0xDEADBEEF);

was unusable. The rest of the changes is just better commenting,
avoidance of variable reuse and so on.

My original patch had the pci_write_config32 -> hide_vpci transformation
(bad), the updated patch (dated 08.05.2008 02:12) didn't, that way I can
send a followup patch which introduces hide_vpci_dev and cleans up the
rest once you ack this one.
