fglrx fails to load on HD6620G/HD6700M

I'm trying to use AMD's opencl on my AMD A8 laptop with switchable graphics.

lspci | grep VGA
00:01.0 VGA compatible controller: ATI Technologies Inc Device 9641
01:00.0 VGA compatible controller: ATI Technologies Inc NI Whistler [AMD Radeon HD 6600M Series]

 

I installs catalyst 12.1 on an ubuntu 11.10 system but xorg falls back to VESA due to a bios read error. Is there some way to blacklist the discrete HD6700M adapter and use only the APU?

 

Than you
