Nope. My box running 5.1-RELEASE now and S3 state works perfect 
except that after resume for some reason it activates CRT instead of LCD.

The only problem I had after installing 5.1-RELEASE
(previous was 5.0-R) is battery state:
I could not get anything, even quantity of batteries.
I've patched DSDT and now everything just fine.
If someone interested I could mail my version of DSDT (for CP/CPi).
