I think I have one of these cards, although I need to break out the
soldering iron in order to remove the shielding box in order to 
verify. Okay I did, it has two chips - an AR5212A-80 and a 

It is usable under NDIS -

 * Generated from net5211.inf and ar5211.sys (307904 bytes)

#define NDIS_PCI_DEV_TABLE      \
        { 0x168C, 0x0012, 0x2022168C,   \
        "Dual-Band Wireless A+G PCI Adapter" }, \
        { 0x168C, 0x0013, 0x2026168C,   \
        "Dual-Band Wireless A+G PCI Adapter" }, \
        { 0x168C, 0x0013, 0x00181737,   \
        "Dual-Band Wireless A+G PCI Adapter" },

but is _very_ fragile - changing the IP address or netmask for 
instance once the interface is 'up' causes traps from inside the
ndis driver image.

I wouldn't mind having a look at what you've got so far. It might
keep me entertained for a few evenings.

The other fun bit that I'm looking a at the moment  pertains to amd64
support as I just recently got one of those systems and it seems as though
there are no performance gains over a straight athlon-xp when it's running
32 bit OS. :( :( ...
