How often is "lots"?  hw tx rate 0x1b is 1Mb/s CCK and 0x1c is 1M w/ 
short preamble.  Both of these rates should be ok to use in 11g so I 
don't see why there are complaints unless the ap you are associated to 
is doing something like forcing 11g-only operation (i.e. OFDM only, no 
CCK).  However even with that you should be fine unless perhaps fixed tx 
rate parameters are set wrong.

Not sure there's a way to dump the negotiated rate set.  You can try 
turning on something like:

wlandebug assoc

to see if that provides useful info.  Otherwise you might need to 
collect a packet trace with something like:

tcpdump -i wlan0 -p -y IEEE802_11_RADIO -w t.pcap

while associating--then inspect the results (and/or send me the pcap file).
