Since I suppose this bug is caused by the ipw2200-firmware which is included in package linux-firmware, I suggest the kernel module in linux (Ubuntu) was never really affected – I filed it against 'linux-firmware' now. According to the linux-firmware changelog the firmware was updated to the current version (3.1) in July 2009.
However, on Ubuntu 11.04 I can still find some of these error messages but I don't really recognize these errors anymore, which means the reconnecting-problem after the firmware error seems to be solved – at least for me.
