Thanks. I've just seen that XFree86 4.3.0 contain a buggy i810 driver. Am now downloading 4.4.0.
I have XFree86-4.3.0-63 installed and have not experienced problems with the driver.
One of the reasons that I use Redhat/Fedora over the other distros is that my video card didn't work on Debian or other distros. It has worked without issues since I bought this computer with RH/F. In short, if it is an XFree86 problem, this distro is the only one that has the secret for this machine.
I have a system that uses the 810 driver. It seems to work alright for me. Included is additional information regarding the monitor. Maybe the monitor settings need adjusted. You might try the section below the monitor information. I doubt you have the exact same monitor.
