Cool - thanks!

I'll have a look through it when I get the chance, try it out, and probably
push it out in my 3.2-gta04 branch.
I've started looking at a 3.3-gta04 branch too (current doesn't suspend
unless you rmmod the wifi driver!!) so I'll add it to that too.

What would be awesome is if you could format the patch as described in: 
   http://linux.yyz.us/patch-format.html
or
   Documentation/SubmittingPatches

- that prepares the way for upstream submission.

The "Signed-off-by" is fairly important though it might seem a bit
bureaucratic. It says "I promise that this is my original work" or something
like that.  I don't doubt that it is, but requiring explicit statements from
all contributors is a valuable safeguard against claims that might be made
about copyright infringement.

Thanks,
NeilBrown
