Display Corruption with ATI radeon 8500

[Caio Boiteux]

Hi
I'm having a very strange display corruption issue that i cant seem to pin
point. sometime without an aparent cause the display gets all garbled with 
some black lines that divide the screen in small blocks (see attached 
picture)

can anyone help me pinpoint it so i can report it in the bug database ?

my machine is a dual PIII 1.4 in a serverworks based chipset and an ATI Radeon 
8500 DV video card 
the system is gentoo, and both driver and Xorg are on the last version (free 
ati driver)

thanks to the awesome suport broadcom has for linux, I cant use my agp since 
its not suported, so altought the board is on the agp slot its in force PCI 
mode

the Device section of my Xorg.conf  is :

Section "Device"
# The Identifier must be present.

    Identifier  "Radeon 8500 DV"
    Driver      "ati"
    BusID       "PCI:1:0:0"
    Option      "BusType" "PCI"
#    Option     "hw cursor" "off"
#    Option     "backingstore" "true"
#    Option     "AccelMethod"   "EXA"
#    Option     "AGPMode"       "2"
#    Option     "AGPFastWrite"  "true"
    Option      "RenderAccel"   "true"
    Option      "EnablePageFlip" "true"
# Enable Clock Scalling to reduce power and heat
#    Option     "DynamicClocks" "true"
    Option      "EnableDepthMoves" "true"
#    Option     "AccelDFS"      "true"
#    Option     "MigrationHeuristic"    "always"
#    Screen     0
