Here it is, embedded in this old email message below.  I know it works for
me (SS5, cg6, Sony GDM20E20 monitor), and it works for the
author (Moritz Bunkus, Ultra1).  I think it should apply to any version
of XF86, because I don't think the cg6 driver has changed for a long
time.

Hello Ferris,

I finally got around to implementing the CG6 screen blanking function
as you suggested. It works perfectly - thanks a lot. I played around a
bit with the various CG6_THC_MISC_* bits and found out that unsetting
CG6_THC_MISC_SYNC_ENABLE really turns the sync off and the monitor goes
into suspend mode (screen is turned off, the standby LED is orange). So
that's all I need (and that is what Solaris does, I think).

I've attached a patch for the XFree sources. Perhaps you might want to
send it to the XFree people so they can include it in the official
source distribution. You seem to have a deeper understanding of
XFree/video hardware issues, that's why I suggest that you send that
patch.

Thanks again for your help, it is greatly appreciated.
