Public bug reported:
Binary package hint: linux-source-2.6.24
in
ii linux-image-2.6.24-16-powerpc 2.6.24-16.30
only the "simple" rate control algo seems to be enabled:
(/boot/config-2.6.24-16-powerpc shows only CONFIG_MAC80211_RCSIMPLE=y)
but according to the following commit, the "simple" RC algo seems to be
seriously flawed:

mac80211: make PID rate control algorithm the default
This makes the new PID TX rate control algorithm the default instead of the
rc80211_simple rate control algorithm. The simple algorithm was flawed in
several ways: it wasn't responsive at all and didn't age the information it
relying on properly. The PID algorithm allows us to tune characteristics suc
as responsiveness by adjusting parameters and was found to generally behave
better.
The default algorithm can be overridden to select simple instead. Which
ever algorithm is the default is included as part of the mac80211
module automatically. The other algorithm (simple vs. pid) can
be selected for inclusion as well. If EMBEDDED is selected then
the choice is available to have no default specified and neither
algorithm included in mac80211. The default algorithm can be set
through a modparam.
While at it, mark rc80211-simple as deprecated, and schedule it
for removal.
