Switching between integrated Radeon 4200 and discrete Radeon 6600M

Hello, all!

Sorry for my English!

I have a problem with switching between integrated Radeon 4200 and discrete Radeon 6600M (actually Radeon 6650M) on HP Pavilion dv6-6030er. In Win7 it is working properly, but in Debian GNU/Linux (testing) it doesn't work. Installed fglrx 11.6 (from unstable repository). There is an option in ATI Catalyst Control Center (amdccle) to switch between cards. It can be changed (and it asks to reboot), but after reboot or Xorg restart it returns back.

My xorg.conf (created with aticonfig --initial): http://pastebin.com/ZkezxQ8H

My lshw: http://pastebin.com/HCV6H9Um

What I can try to do?

Also I tried to change

BusID "PCI:1:5:0"

in my xorg.conf to

BusID "PCI:2:0:0"

(see my lspci -nn output). But after that I got segmentation fault: http://pastebin.com/6psjDc8S

Sorry, this is my Xorg.0.log with default xorg.conf.

Yeah! It is working with fglrx 11.7. But in 11.7 most (every?) 32-bit 3D applications segfault.
