Same thing here vchewjr. From what I've read on this forum (and CoH's forums) it's a VERY common problem. Even with Desktops running an ATI card. To put your mind at ease, here's the scoop:
I have a Sager (well Hypersonic GX7) 8790 and I was experiencing CONSTANT lockups in CoH and Call of Duty when using the "official" drivers. I thought it was most likely a heat issue, but even with the fans on full blast it kept doing it. So I decided to try the Omega drivers (at the suggestion of many users on here). BOOM. Lockups gone. Call of Duty is flawless.....played for hours on multiplayer with not one problem. Then I fired up CoH. 1st thing I noticed....substantial framerate hit. I turned the details down and got things a little more under control, but then I noticed all the flickering buildings and strange textures popping up on roofs and roads. It's not the end of the world, but it is very annoying. Anyhow.....it DID stop the lockups.
On my desktop I have a Radeon x800 XT....the mac daddy video for ATI users, and guess what? I still get the crazy flickering buildings. Turns out it's a known "problem" with ATI's last driver update and should be corrected next release (which should be out ANY time because the beta version is available for all the DOOM fans).
So that's great news for my desktop, but what are we supposed to do about our Sagers? Here's what I'm gonna do. As soon as ATI "officially" releases the new Catalyst drivers, I'll download that and use the driver mod utility (

I just don't have the time or patience for Sager to stay a full two driver sets behind ATI's official releases. That just makes crazy problems for gamers.
