One thing I forgot to mention: in 2.6.25 zd1211rw is moving away from ieee80211/softmac and changing to mac80211. I'm not sure if mac80211 has been tested on architectures with alignment constraints, so we may be greeted with new problems.

Or some might go away. Speaking only from memory, I think the code with compare_ether_addr problem that David found is not present in the mac80211 port.
