No-one can say that, the driver is buggy. Something to do with waking the card 
up or bringing it out of deep sleep. Personally, I think it's along the lines 
of a race condition in how the card is reliably powered up (but that's just 
be thinking of what's most likely). Intel has a bugzilla, which shows that 
virtually every distro on all platforms using the 3945 have the identical 
problem in every kernel version that contains this code:

We have two options:

- get involved, fix it ourselves, submit patch to upstream (intel)
- wait for intel to come up with reliable code

All the evidence points to intel taking this seriously, it's a popular card 
and intel wants their stuff to work nicely on linux. So chances are it's a 
deeper problem that it appears on the surface
