opencl

I have a HP Envy 4 1025tx with Hybrid graphics. Although this is a 64bit system, I've installed 32bit Ubuntu on it for some reasons.(Hybrid graphics don't do well with 64bit Ubuntu.-"Some one on some forum")

I had heating problems with the GPU but I've fixed them all with vgaswitcheroo. But now I wanted to use my Blender on my Ubuntu. To my surprise Blender didn't detect the dedicated 7670m card in my machine. I've confirmed with

cat /sys/kernel/debug/vgaswitcheroo/switch

Both IGD and DIS were up and running. I dont seem to have libopencl on my /usr/lib even though my synaptic manager says that I have installed it. I'm not quite sure what I've installed. It says that I've installed "ocl-icd-libopencl1".

So my question is...

Do I have opencl on my system?

If not do I have to get propreitary ATI drivers for sake of opencl(fglrx wrecks up my unity totally on my system I need directions to fix it if this is the choice)?

Should I get a 64bit Ubuntu installed on this system?
