On my machine (128MB RAM, tnt2pro/32MB, Xfree4.0.1,Nvidia
GL-drivers0.95) I have the effect, that the X-server process takes up
about 256MB of RAM, and applications that use GL are shown up with about
200MB of RAM (as shown with qps)

I think it's the GL-driver, maybe it let's see the applications all
possible AGP-memory or whatever?

I've looked more closely with qps at the memory maps of the GL process.
/dev/nvidia0 is listed three times with 64MB memory usage and once with
1MB memory usage....?

The X-server takes up 3x64MB (on /dev/nvidia0) and 32MB on /dev/mem

All other apps (and X-apps) that don't use GL have a 'normal' memory
size.
