Hey, Vangel, I have a similar situation.

One year ago, I bought Acer with notebook with Optimus. Then, I realized 
that it wasn't for Linux... I changed it for a Pavillion dv6 3160us, 
with 4250 and 5650 ATI cards... thinking PowerXpress DID work on 
Linux... I couldn't ever used the discrette card with Catalyst, nor 
OpenSource Drivers.

The best configuration I was using was: Ubuntu 11.04, Catalyst 11.6. 
There were some artifacts moving some windows, viewing video with 
hardware acceleration and using a 3D engine (Blender)... but the 
computer worked for my needs (look at it: http://vimeo.com/35154176, at 
minute 1:00 the digital puppet starts).

Since I get the HP, I tested Catalyst 11.7, 11.8, 11.8, 11.10... Ubuntu 
10.04, 10.11, 11.10... Mint... and in any of these software configs, 
couldn't use Blender (edit mode) because of visual errors. In Blender, 
the display had a ONE-EVENT-DELAY. This mean that, if I pressed a key, 
it display the change in the screen not at the moment, but the next time 
I press another key (or mouse click). All the events has that delay... 
yes, I know, it's very strange.

I test vgaswitcheroo in Ubuntu 11.04... nothing. There's no way to use 
change to the discrette. And the open source drivers are really slower 
than the proprietarie's.

Then, Ubuntu 12.04 arrived... and the last version of Catalyst. The 
discrette card still does not work, but: The hardware video acceleration 
is OK. Blender works OK. Only few artifacts on moving Blender windows... 
but now... I HAVE AUDIO PROBLEMS! I'm using Jack and have XRUNS (buffer 
under-or-overrun) that I didn't have before.

(Vgaswitcheroo doesn't work in Ubuntu 12.04)

I repeat... Discrette card still does not work. I've used the 4250 
integrated card.... but spend so much money to have the 5650.

Fuck you, ATI. Fuck you, HP.
