Haha, the AP is broken.  Its does not use single TX seq (as required
by 802.11-1999 R2003, same as 802.11e for non-Qos data and bcast mgt)
for data and mgt packets.  Your AP seems to use one TX seq for beacon
(99% of mgt packets) and another TX seq for data.  That also explains
why using lower rate will have better result: number of retries is
reduced and duplication detection is performed only on retried
packets.
Please test following patch and see whether it makes the situation
better in 11g mode:

Testing now, will let you know of success or failure within the next day 
or two. If this worked out to be the fix, I shall call you Sir Genius 
from now on :D

Thanks!!!
