Frozen Vaio VGN-FZ320E and OpenSUSE

Hi all,
A have some experience with linux, but I really don’t know what happening with my notebook and the OpenSUSE.
I have a Vaio VGN-FZ320E (Intel Dual Core, 2GB DDR2, HD 200 Sata, Video Intel 965, Wireless Intel 4956 / Ricoh Webcam)
I’ve tested with OpenSUSE 11 (both 32 and 64 bits , the results are same).
What results?
The linux installs ok. Everything is looking fine… suddenly the linux freezes. I need to shutdown with the power button cause don’t have any response from pointer or keyboard.
When I come back, there are no message related in the system logging. When I use the OpenSuse virtualized (VMWare)at Windows Vista Host, everything is fine… no freezing (but slower (You can imagine that! :-)))

Does anyone have any issues like that?

I really want to use this amazing OS native in my laptop.

Thank you for your patience.
