Atheros card in HP Pavilion dv5000

[M. Warner Losh]

What do I need to do to get around the ***STUPID*** bios restriction
that is in my HP Pavilion dv5000?  I have a broadcom unit:

none3 at pci6:2:0: class=0x028000 card=0x1358103c chip=0x431914e4 rev=0x02 hdr=0x00
    vendor   = 'Broadcom Corporation'
    device   = 'Dell Wireless 1470 DualBand WLAN'
    class    = network

but there's no driver for it.  I have an atheros minipci card, but
when I put it into the laptop, I get "unsupported wireless card
detected" message.

How can I install the atheros card and have it work?
