You could run the vesa server until your gfx becomes supported (as I 
am). I have the same issue, an AMD jaguar CPU, w/ integrated gfx (Kabini 
[Radeon HD 8280 / R3 Series]), which I knew to be unsupported when I 
bought in last April 9, the day it was released to the public :-). I 
plan on using this box for years, so I am patiently waiting for xorg to 
catch up to this APU, whereupon I should be happy for years to come .... 
$0.02, no more, no less ....

 From my xorg.conf:


Section "Device"
         ### Available Driver options are:-
         ### Values: <i>: integer, <f>: float, <bool>: "True"/"False",
         ### <string>: "String", <freq>: "<f> Hz/kHz/MHz"
         ### [arg]: arg optional
         #Option     "ShadowFB"                  # [<bool>]
         #Option     "DefaultRefresh"            # [<bool>]
         #Option     "ModeSetClearScreen"        # [<bool>]
         Identifier  "Card0"
         Driver      "vesa"
         VendorName  "Advanced Micro Devices, Inc. [AMD/ATI]"
         BoardName   "Kabini [Radeon HD 8280 / R3 Series]"
         BusID       "PCI:0:1:0"
EndSection


I added the vesa line, the rest was already there ....
