wicontrol TX patch

Hello
My questoin is about status of wicontrol TX power control  in current ?
Anybody planing to commit it into wicontrol ?
I use modified patch from "imp" for three months
it works well, but problem is, that if card is reseted by wi_reset - i 
guess,
value from register is owerwrited by default (I think ALC also turns on)
any ideas/solutions how keep this TX power value after card reset ?
for this time I use cron to  periodicaly refresh TX power ..
sorry for my english ;)
thaks for reply
Jiri
