Great - Thank you for working on this :)

However, after having upgraded my ThinkPad X60s to todays -current and
performed the above changes, this appears in my dmesg at boot time:

The above list of channels which can not be reset re-appers
periodically, I assume in connection with background scan. They also
appear during regular scans, e.g. when wpa_supplicant scans for a
suitable AP. Whenever the messages appears, the connection to the
currently associated AP dies (although it still appears to be
associated according to ifconfig).

The periodic messages disappears when bgscan is disabled on wlan0.

Below is the list of channels supported by my card:
