Hi,

Just bought an Asus P5Q Pro and your driver will come in very handy very
soon 8)
I'm installing the system from scratch with an fxp in the meantime so I'll
give you feedback as soon as I can get some CURRENT compiling with your
driver in it.

My card: class=0x020000 card=0x82261043 chip=0x10261969 rev=0xb0 hdr=0x00

Many thanks for your work!
