Sounds similar to what happens to me (except the flash/firefox thing).
It happens with graphics heavy stuff and during heavy compiles
(kernel..). Mouse is only sometimes responsive for a few seconds.
thought it was gone with 2.6.29 but it came back after a few weeks..

I'm pretty sure it's hardware related, overheating or something with
graphics since it also happened when I had installed windows a few
years ago to play at a LAN-party.

Now it starts to get annoying, I'm just waiting for the perfect laptop
that can be used as audio workstation..
