ThinkPad X40 (2371-H9U) - Atheros attach fails?

[James Snow]

I've got 5.3-Rp4 up and running on my X40. X works, onboard gigE
works. Stable after using the "boot into Windows and disable the
secondary IDE bus" hack that seems to be necessary on most X series
ThinkPads.

But the onboard Atheros card fails to attach. At boot I get:

pci2: <network, ethernet> at device 2.0 (no driver attached)

If I kldload if_ath:

ath0: <Atheros 5212> mem 0xd0200000-0xd020ffff irq 21 at device 2.0 on pci2
ath0: mac 5.9 phy 4.3 5ghz radio 3.6
ath0: unable to collect channel list from hal
device_attach: ath0 attach returned 22

And pciconf -vl:

ath0 at pci2:2:0:  class=0x020000 card=0x057e1014 chip=0x1014168c rev=0x01 hdr=0x00
    vendor   = 'Atheros Communications Inc.'
    class    = network
    subclass = ethernet

Any pointers on what to poke at next?
