I have observed similar symptoms on HPC nx6325, although I haven't managed
to get the adapter associate with an AP.

This is a PCI-E card so I need some additional patches to make the driver
detect it, and I use the firmware cut from wl_apsta.o. The kernel is also
64-bit, 2.6.18-rc6-mm2.

lspci -v:
