hmm, several weeks ago? Not alot was changed in the last few weeks,
sure there was the rssi->dbm update (I hope you've already updated
your eeprom image.) Then p54_flush and some tx_flag updates, but
the driver's PS code was not touched.

No idea, it looks like the ps-poll is broken, because
"iwconfig wlanX power timeout 10" fixes the long delays
almost immediately. [let's see if there's more]
