Causing problems when going to alternate terminal (Ctrl-Alt-F1..F6)

After upgrading (not clean install) from Fedora Core 6 to Fedora 7, I now have problem.

How do I completely disable DPMS?

Here's what I've tried, with no success:
1. Deleted acpi RPM package (didn't think this would have anything to do with behavior; it didn't).
2. Commented out xorg.conf Option "dpms" in Monitor section.
3. Deleted xorg.conf Option "dpms" in Monitor section.
4. Typed Option "dpms" "false" in xorg.conf Monitor section.
5. Typed Option "DPMS" "false" in xorg.conf Monitor section. (Case sensitive?).
6. Typed Option "dpms" 0 0 0 in xorg.conf Monitor section.
7. Edited /etc/gdm/-all- Default shell scripts (Init, PostLogin, PreLogin, PostSession):
7a. Included xset -dpms
7b. Included xset dpms 0 0 0

None of those worked, and every time, Xorg.0.log has:
(II) Loading extension DPMS
(II) SAVAGE(0): DPMS capabilities: StandBy Suspend Off; RGB/Color Display
(**) SAVAGE(0): DPMS enabled

Is it possible the S3 Savage driver has DPMS enablement hardcoded?

Any ideas how to get DPMS disabled?

Maybe it's running as a service. Or it could be in your bios.
