Which GUI are you using? Q Windows, or Photon or ...?

In Q Windows there is refresh_s3 utility (used in sysinit) for S3 Trio 32,64 graphic cards. If you use gr.phi (i.e. you use Photon graphic "drivers" in Q Windows), you can easily set mode (640x480, 800x600, 1024x768, ...) and refresh rate in Photon QNX - Picture Settings. ATI Radeons 7000 are fully supported.
