BTW I upgraded the CVS source on my laptop a 770Z and started to get
the flicker.  So a change was made that causes this.  I went back
through the CVS changes and found if I backed out one change the flicker
went away.  So if you can grab the sources and apply this it should
help.  Or for kicks you can get 
	http://www.ambrisko.com/doug/trident_drv.o
and install that /usr/X11R6/lib/modules/drivers (backup the original).
I think it may work even though it is built on FreeBSD.

Also let me know if you have a mouse problem (ie. it disappears after
a "tput clear".  I have a work-around patch for that as well.
