Leaving the computer running for 24h gave no signs of any kind of
issues, besides a few AP timeout after 500ms.

If you wish me to further test more patches, please do include me in CC.
However, my access to the 3945 hardware is now very reduced, so I'll
probably take several weeks to test the patches, if at all.

Thank you for your patience, time and code since my first half-made
debugging of the HW scan crash in the iwl3945 firmware :)
