Subject: asus-laptop kill wifi when initital

Hi,

I have a report[1] that user has to blacklist the asus-laptop otherwise wifi
can not work. I copied asus-laptop.c from 2.6.32 kernel and remove two
lines[2] that set WLED/BLED on. The modified driver works fine.

User uses 2.6.32 based kernel and when 2.6.34, a module parameter
"wifi_status" is added[3] to let user choose what he want to do on WLED/BLED
when initial. So I guess there are some reports tells the parameter for
WLED/BLED maybe changed. Since the default action is still on because some
machine need to enable WLED/BLED when booting. Any idea for the future
change? For example telling user add an options on /etc/modprobe.d, or try
to have a list of machine that not to set WLED/BLED to 1 when booting?
