Comment(by pgf):

 as a workaround, during testing, for the leak, as well as a way to
 exercise s/r of the wireless
 without powering it down, use something like:
 {{{
 while sleep 2
 do
   echo $((i++))
   free
   ethtool -s eth0 wol u
   echo mem > /sys/power/state
 done
 }}}
 (if you don't want the wlan to wake you, you'll probably need to down the
 interface.)

 re: the leak -- the code in if_sdio_prog_firmware() seems to be doing the
 right thing, and does free the (two separate chunks of) firmware data when
 finished.  still looking.
