I've got the same issue on my 900A, though I've never ever been able
to successfully switch the card on with linux > 2.6.26.

linux-image-2.6.30-1-686 2.6.30-5
eeepc-acpi-scripts 1.1.1

If I boot with wifi on, it is OK, ath5k loads fine and the wifi works.
Switching wifi off for the first time:
---- /var/log/syslog: ----

Switching on doesn't seem to do anything. Forcing the interface down
(ifdown --force) kills running wpa_supplicant etc. Afterwards, trying to
bring it up results in this:

Script started on Sun 02 Aug 2009 05:50:42 PM CEST

SIOCSIFFLAGS: Input/output error
wpa_supplicant: /sbin/wpa_supplicant daemon failed to start

run-parts: /etc/network/if-up.d/wpasupplicant exited with return code 1

Script done on Sun 02 Aug 2009 05:50:43 PM CEST

During that time:
---- /var/log/syslog: ----
Aug  2 17:50:42 zriebae wpa_supplicant[3301]: Could not set interface 'wlan0' UP

---- end ----

Doing this over and over again, I get always the same results, only the
order of messages in syslog is a bit different sometimes. (Sometimes
wpa_supplicant complains first, sometimes it is ath5k.)

There's no reference to ath5k or madwifi in /etc/modprobe.d/,

If there's something else I can try, let me know.
