[radeonhd] Unknown card detected: M76

I have a M76 in a HP Compaq 8510 that now works with commit 1235392f, but it throws an unknown card warning in my Xorg log which I have attached. Here is the output of lspci -vv: 01:00.0 VGA compatible controller: ATI Technologies Inc Unknown device 9581 (prog-if 00 [VGA]) Subsystem: Hewlett-Packard Company Unknown device 30c5 Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast>TAbort- SERR- _________________________________________________________________ Put your friends on the big screen with Windows Vista® + Windows Live™. http://www.microsoft.com/windows/shop/specialoffers.mspx?ocid=TXT_TAGLM_CPC_...
