Ah! Thank you again.

	Currently I have extra enabled and community-testing enabled so I do expect things to break. The xf86-video-ati 6.12.99.git20091221-1 package works fine for me except for the mesa/hardware issue. The resolution killer turned out to be libdrm-2.4.17-2.

	For some reason the libdrm package just ignored the 1440x900 display data. I think all would work find if I could get the resolution set. I'll tinker some more.

	If anyone has any idea on how to set the resolution at 1440x900 with the new libdrm, I would welcome any thoughts. I have tried:

Section "Monitor"                               
        Identifier   "Monitor[0]"               
        VendorName   "TOSHIBA"                  
        ModelName    "TOSHIBA 17IN TRUEBRIGHT"  
        UseModes     "Modes[0]"                 
        DisplaySize  367        230             
        HorizSync    30.0 - 70.0
        VertRefresh  43.0 - 60.0
        Option       "CalcAlgorithm" "XServerPool"
        Option       "DPMS"
        Option       "PreferredMode" "1440x900"
EndSection
Section "Modes"
  Identifier   "Modes[0]"
EndSection
Section "Screen"
  DefaultDepth 24
  SubSection "Display"
    Depth      15
    Modes      "1440x900" "1024x768" "800x600"
  EndSubSection
  SubSection "Display"
    Depth      16
    Modes      "1440x900" "1024x768" "800x600"
  EndSubSection
  SubSection "Display"
    Depth      24
    Modes      "1440x900" "1024x768" "800x600"
  EndSubSection
  SubSection "Display"
    Depth      8
    Modes      "1440x900" "1024x768" "800x600"
  EndSubSection
  Device       "Device[0]"
  Identifier   "Screen[0]"
  Monitor      "Monitor[0]"
EndSection
Section "Device"
  BoardName    "RS690M"
  Driver       "radeon"
  Identifier   "Device[0]"
  VendorName   "ATI"
EndSection
Section "ServerLayout"
  Option       "Clone" "off"
  Option       "Xinerama" "off"
  Screen      0  "Screen[0]" 0 0
EndSection
Section "DRI"
    Group      "video"
    Mode       0660
EndSection
Section "Extensions"
        Option      "Composite" "true"
        Option      "DAMAGE" "true"
EndSection

	And... a number of variations to the above from what you see above down to the bare minimum of:

Section "Device"
  BoardName    "RS690M"
  Driver       "radeon"
#  Driver       "radeonhd"
  Identifier   "Device[0]"
  VendorName   "ATI"
EndSection

	but still no joy....
