I'm having random freezings.
*They can happen after hours of booted or just minutes => totally random
*No logs anywhere
*Mouse keeps moving and can be controlled by pad/usb
*SSH remote connection establishes perfect, can execute TOP command and everything seems keep working normally.
I'm confident this is a problem with GMA x3100 144mb 0x2a02.
My notebook is a Gateway M-series (m-6880):

I have the very same problem as you are.
My CPU is the same with GMA X3100 (2a02) - Rev 03.
Yes I can still hear sound (iTunes playing) when the graphic is freeze (mouse cursor still function).
SSH to the machine still works perfectly...
And most of it not error log that related to this graphic stuff...
It's usually it's happen when I'm using application or the Mac OS X function that have the need of using the
graphic function. Such as Photoshop, Playing Games, and some random events with the OS it self.
Right now on Lion, I was trying to make it more stable by avoiding any extensive use of graph function,
like using tools to turn off any animation (TinkerTool app / Cocktail app will do), turning off the window shadow (ShadowKiller app - I have this run on as Login item).
Oh ya the mouse lag problem solve by the solution given in this thread post.
I have this random graphic related freeze since Leopard (10.5.*), then Snow Leopard (10.6.*) (more stable though, less often to freeze) and now with Lion (10.7.0 - the update for 10.7.1 didn't issue any graphic function update)...
This is irritating bug with the graphics
So, do you (or anyone) happen to know a solution of this (random freeze) until now?
