Lost Sync Problems

I have a problem where as of about 2 weeks ago my laptop can't drive a
second monitor in Xorg.
I have a dual-monitor system setup with my laptop... the internal screen
is one and an external LCD is another...
Before two weeks ago I had an issue where occasionally (once every few
days), the LCD would say it had no sync, and a yank of the power cable
and a re-plug would fix it. This happens to me on more than one of this
brand of LCD. I have no other brands to try with. It doesn't happen on CRTs.
However, a week ago, it happened and I couldn't get it to sync up
anymore. The monitor works on other systems just fine, but I can't get
it to sync on this one. I tried a CRT, and it won't sync there. HOWEVER,
it will show console mode on both screens just fine.
My X configuration uses Xinerama... and has worked for about 5 months
now until 2 weeks ago.
I tried hooking the secondary monitor up through both the docking
station and the VGA port directly on the laptop.
My laptop is Dell T42
My video card is a ATI RV350 Mobility Radeon 9600 M10
The monitors I've tried both work on other systems are are:
LCD: Planar PE1900
CRT: NEC Multisync FP955
I'm running XOrg 6.9.0 - or more specifically 6.9.0.dfsg.1-4 (from
Debian) on a 2.6.14 kernel.
My config looks like this:
Section "Files"
FontPath "unix/:7100" # local font server
# if the local font server has problems, we can fall back on these
FontPath "/usr/lib/X11/fonts/misc"
FontPath "/usr/lib/X11/fonts/cyrillic"

Any help would be greatly appreciated. Thanks.
