Hmm, on my experience, software sucks much more than hardware, but we
never can exclude hardware problem. I'm not sure if there are divergence
between iwl4965 chipsets. Also I'm not sure if there are more than one
chipsets revision at all. Christoph, you mentioned that you replaced you 
motherboard. Did the problem start to happen after that? Did you
correctly connect antennas cables to adapter. Does adapter sits
tight in the mini PCIe slot?

No, that's not needed if there are no good logs for compare. If possible
try on some very old kernel, first kernel with iwl4965 support was 2.6.24.

Thanks
