I saw you use "radeon.modeset=1" in your boot command, I use "video=radeon:2048x1536-59.4", and I suspect a goof on my own part. > Again, I appreciate you taking a look.

First I recommend weed out all X goofs. I have my current 2 FG boxes a 3.2GHz (hyperthreaded) P4 w X850XT-PE is slower than my single threaded Athlon XP 3000+ w 9800Pro, which is not much faster than my old AMD K-2 450_M_Hz w an 128 bit 9250 in a _2_x AGP slot, I should see a 10 to 30 times higher frame rate on my current gear with a similar success. -- ..med vennlig hilsen = with Kind Regards from Arnt... ;o) ...with a number of polar bear hunters in his ancestry...
