Just tested n900 wlan here and it's working for me with Emil's
patch from the "" thread and the PM runtime regression fix for
hsmmc I posted earlier today. Looks like n900 is hitting off
mode just fine with wlan0 configured.

It does not wake up to pings from outside from off mode though
until the system wakes up.

I'll take a look and send a patch for that separately.
