Compaq have this really crack-smoking idea about how the pcibios is supposed to work. In a fit of brilliance, some rocket scientist decided they need filter out all the host->pci bridge entries. This hoses *all* the larger compaq DL and ML series, eg: DL360, DL380 etc. The DL320 appears fine though. Current will not work either, unless you use ACPICA to get the correct PCI routing. We have argued with the compaq bios folks before. Do you have a support contract by any chance? I can give you explicit details if you wish.
