ndis0: link down after idle time

[lreid at a.cs.okstate.edu]

Hendrik - are you certain it is a rev. B3 with the ar5213 chipset? The
ath driver on my box attempts to hook, but fails. I get these kernel
messages:

ath0: <Atheros 5212> mem 0xd6800000-0xd68 0ffff irq 5 at device 10.0 on
pci0
ath0: unable to attach hardware; HAL status 13
kernel: device_attach: ath0 attach returned 6
