[Gta04-owner] suspend with QTMOKO or SHR

[arne anka]

thanks a bunch!
but apparentyl that's more or less happens already -- at least it does not  
change anything.
if i do those two calls in bash, the device still does not go down and  
still wakes up (if it ever sleeps) when tocuhing the screen.

i have the dim recollection that i got some hint to another mail where i  
mentioned this besides a bunch of other issues, but i can't find that mail  
again :-(
