Thanks for the information. Dropping the color depth to 16 does indeed fix the hard locks on both systems, suspend-to-whatever, the screensaver, OOo and firefox can all run without hanging the system now.
First time i've been able to use my machine for more than a few hours without a hardlock in months.
As for the artifacts, I have no idea why, but after adding:
Option "AGPMode" "2"
To the Device section of my xorg.conf file (found on one of the numerous 'how to get performance out of your ATI card sites' out there) -- everything seems to work normally.
