What kind of radeon 32MB is this? I have one and it has no support for either quartz or Core Image.
Also, try Firewire Disk Mode on yours, mine will shut itself down when I try it.

CLEARLY there is something wrong in the board but Apple Hardware Test said there wasn't. :?:

Do you have a hard drive set as master plugged into the primary IDE bus? IIRC there was a kbase article describing unexpected behavior in TDM if there was no master disk on the primary IDE controller on macs. Exact same thing happened on my iLamp 800 until I took it apart and discovered that the DVD-RW drive was set as master and the hard drive as slave. Setting them vice-versa allowed TDM to work again!
