The HP BIOS allows a small set of PCI IDs. Usually, some Intel cards will be 
allowed as well as some Broadcom units.

Does the BIOS allow the wifi device to be disabled?

If unitedriders has access to any other wifi card that will fit in the slot, 
then the BIOS can be used to test the slot. If the other card is recognized, 
then the BIOS error message will appear. That will definitely say that the 
problem is not the bridge or the PCI adapter. I guess this machine has mini-PCI, 
not mini-PCIe.

The only other possibility is that all the hardware is good, but the kernel 
cannot drive the bridge to which the BCM4311 is attached. Does the dmesg output 
have any indication of this?
