I can now confirm that it is indeed the kernel causing these trouble. I installed the kernel linux-image-2.6.31-21-generic from karmic-updates, and my wireless connection is again rock stable. Of cause installing a kernel from an old version of Ubuntu is kind of worrying, but a part from a broken boot splash screen I have seen no ill effects.
Since I do not own this bug, I can't change the package it affects, but it should probably be set to the kernel, and perhaps iwl3945 should be mentioned in the title, in the hope that somebody responsible for those parts sees the bug :-)
