I'm beginning to suspect that this is in fact a bug in SDL. Quake III and
RtCW can change resolution to 800x600 from my desktop 1024x768 without any
problems. Here's what my XFree86 log says when I try to run RtCW at 800x600:

SwitchToMode - scrn: 0 clock: 56300
                hdsp: 800 hbeg: 832 hend: 896 httl: 1048
                vdsp: 600 vbeg: 601 vend: 604 vttl: 631 flags: 5
Checking against clock: 94500 (94500)
                  hdsp: 1024 hbeg: 1072 hend: 1168 httl: 1376
                  vdsp: 768 vbeg: 769 vend: 772 vttl: 808 flags: 5
Checking against clock: 56300 (56300)
                  hdsp: 800 hbeg: 832 hend: 896 httl: 1048
                  vdsp: 600 vbeg: 601 vend: 604 vttl: 631 flags: 5
(II) NVIDIA(0): Setting mode "800x600"
SwitchToMode - Succeeded

Quite some difference. People are running into the same problem with the
NWN beta which also uses SDL. Does SDL not like XFree86 4.3?
