[ltp] Moving Video Won't Display on External Monitor of Thinkpad R32

[morpheus]

Thanks, Matt, this solved the problem.
If anyone else is having the same problem let me know and I'll send you
my XF86Config, since editing XF86Config can often be an artform that
requires lots of trial and error.
Also, keep in mind that you need to add the Option "OverlayOnCRTC2"
"true" in the SECOND "Device" section (if you set up multihead you'll
have two "Device" sections).  If you put it in the first, it doesn't
work...took me a while to figure that one.
