"binks" when using newer kerels

[Diego Iastrubni]

Hi all,

I am using Mandriva 2008.1 (yes, the old one) and decided to upgrade my 
kernel. I tested 2.6.29 and 2.6.30 (git, from Linus branch) nad under both I 
get random "blinks" in the screen. It's like the screen gets shut down for 
100-200 msec, and then continues on working. 

The machine is a Lenovo 3000 N100, with an Intel 945 video card.

Before I start hunting for this bug... as anyone seen it, something similar... 
or has an idea?
