There's a report in bugzilla from Ed Fardos about problems that can happen
if DPMS is enabled (with xset) while the screen isn't blanked.
I can think of several ways to handle this. One is to force screen
blanking everwhere DPMSSet(level) with level != DPMSModeOn is
called. However, the easiest is probably to handle it in DPMSSet()
with something like this:

Since XFree86 is the only DDX in our source tree that implements DPMSSet(),
this would be the simplest way to do it pre-4.4.
Any comments?
