And I guess your AP is configured to use some 2.4GHz channel? Revision 1.33 enabled 11a support, which means scans will take much longer since more channels must be scanned. With if_iwm.c at HEAD, if you run 'ifconfig iwm0 media autoselect mode 11g' before doing anything else does it behave better again?
