I believe the model you mention is a wide screen model, with a native resolution of 800x480 (not 800*600).

This is probably the reason why every looks a bit squashed. Try setting the screen to 800x480 instead.
If it is a wide screen model, its probably time to look at the "profile_scaling" options in the touchbuddy.cfg file.
