Getting ath5k driver working with Thinkpad T61 [168c:1014]

["Zack Weinberg" <zackw@panix.com>]

I have a shiny new Thinkpad T61 and I'd like to get its wireless
chipset working with the ath5k driver.  I have tried
compat-wireless-2008-05-07 on top of kernel 2.6.25.1 -- I get this in
dmesg:

# modprobe ath5k

ath_info does not work:
# ath_info df3f0000
Unable to read EEPROM Magic value!

The old madwifi drivers don't work with this chip either:
# modprobe ath_pci

[  392.385870] ACPI: PCI interrupt for device 0000:03:00.0 disabled

What can I do to help make this chip work in the near future?
