Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.Install 7.1 on Dell Inspiron 2500
2.Select 16 bit 800x600 as video mode
Actual Results: The machine locks hard on any 16 bit mode.

Upgrading (from raw hide) to the latest XFree86 (4.1.0) and upgrading to a
more recent kernel (2.4.8) allowed 16 bit display at 800x600.
