I have been having the exact same problem and I finally figured it out.
I have an nVidia GeForce GO 7800 GTX card with 256mb ram. A fully capable
card. I was running it at 1920X1200 res, and no matter what, I had no options
for using Aero.
Out of frustration I swtiched it to 1280X1024 and presto! Aero is now
available and active. I even swtiched back to 1920X1200 and Aero is still
working and configurable. Hope this helps.
