I thought I would give the ath5k driver a shot on my Thinkpad T60p to see
what happened but it wasn't particularly successful. lspci -v shows

03:00.0 Ethernet controller: Atheros Communications, Inc. AR5212 802.11abg NIC (rev 01)
        Subsystem: IBM ThinkPad 11a/b/g Wireless LAN Mini Express Adapter (AR5BXB6)
        Flags: bus master, fast devsel, latency 0, IRQ 22
        Memory at edf00000 (64-bit, non-prefetchable) [size=64K]
        Capabilities: [40] Power Management version 2
        Capabilities: [50] Message Signalled Interrupts: Mask- 64bit- Queue=0/0 Enable-
        Capabilities: [60] Express Legacy Endpoint IRQ 0
        Capabilities: [90] MSI-X: Enable- Mask- TabSize=1
        Capabilities: [100] Advanced Error Reporting
        Capabilities: [140] Virtual Channel

During boot, the following relevant information in dmesg shows up;

ACPI: PCI Interrupt 0000:03:00.0[A] -> GSI 17 (level, low) -> IRQ 21
PCI: Setting latency timer of device 0000:03:00.0 to 64
Uhhuh. NMI received for unknown reason b1 on CPU 0.
You have some hardware problem, likely on the PCI bus.
Dazed and confused, but trying to continue
ath5k_hw_nic_wakeup: failed to resume the MAC Chip
ACPI: PCI interrupt for device 0000:03:00.0 disabled
ath_pci: probe of 0000:03:00.0 failed with error -5

Needless to say, it fails to bring up networking later. I have no real idea
how to debug something like this. Any suggestions?
