Ok, think I understand cgminer a bit better, but can't get it to connect to stratum.bitcoin.cz:3333, says "no live pool" and gpus do not start.

My command line is:
cgminer -o stratum.bitcoin.cz:3333 -u [my worker id] -p {my worker wd] --shaders 1024 --intensity 17,17,17 --worksize 256,256,256 -g 1

I tried the same command line except with --scrypt flag and connection to LTC pool, all gpus fired up and pumping 275 KH/s each.
