wpi error: bus_dmamem_alloc failed to align memory properly

[vittorio]

Context: HP laptop DV6000, centrino duo, FreeBSD 7.0-BETA4
When loading if_wpi I get the following line saying that "bus_dmamem_alloc 
failed to align memory properly"
<SNIP>
wpi0: <Intel(R) PRO/Wireless 3945ABG> mem 0xd8000000-0xd8000fff irq 16 at 
device 0.0 on pci2
bus_dmamem_alloc failed to align memory properly.

Therefore I'm unable to make wpi0 work at all.

Could you please tell me what should I do?

Ciao, Vittorio
