Their is no problem when going to sleep-modes.
When resume the session their are all coloured blocks and stripes, and the
session seems to be hanging/freezing.

I have tried the Linux Kernel 3.5 and Linux Kernel 3.6, latest nouveau-drivers
but the problem still exist.

You can see the problem here:

I never had this issue with the official nvidia drivers, but I haven't tried it
yet because this is running on an UEFI-system.

Hope the issue can be fixed. :)

Thanks.
