Angry ATI Radeon Xpress 1100 Stuttering Graphics

I am pulling out whatever hair is left on my head trying to isolate an issue I'm having with my Acer Aspire 5100 with Xpress 1100 graphics (256MB shared).

My system specs:

Acer Aspire 5100 laptop
AMD Turion MK-38 2.2GHz CPU
2GB DDR2-5300 RAM
ATI Radeon Xpress 1100 (set to 256MB shared)
Windows Vista Home Premium 32-bit

Basically I want to run some games on it. I know it's not a powerhouse of a GPU machine, but the stuff I'm trying to run is not real graphically taxing. That being said, I have successfully run Half-Life 2 and C&C 3 without much issue as long as I dumb down the graphics and resolution.

However, when running Civilization 4 or a flight sim called Enemy Engaged Comanche Hokum (from 1999), the graphics are choppy. FRAPS shows a constant FPS of 30+, but visually the graphics stutter intermittently, but frequently.

I have the latest ATI drivers installed too (as of 8/13/07 7.8 just released).

Additionally, every time I go to install the Catalyst driver suite, it always shows that "Southbridge Filter Driver" needs to be installed, and even though it is selected, next time I run the Catalyst software with "update" mode, it always shows that it needs to be updated. What is this "Southbridge Filter Driver" anyways?

Thanks a bunch!
