I don't know which miner you are using, but I am using guiminer. There is a spot that says device. Before I updated my ATI driver only the cpu was listed. At first I thought 4 Mh/s was good, (maybe for the cpu it still is). Make sure you have it updated. Because 2Mh/s is really low. Don't expect to get anything with that. Without overclocking my ATI 5770 I get 150-165 Mh/s.
You should be getting way more that 1.6mh/s with that card. Sounds like something is wrong with your setup.

Something else I've noticed, on 11.6 while mining and watching flash videos, my gpu used to clock back from 1GHz to 300MHz. Now it only clocks down to 900MHz. This could've been done in .7 or .8 I guess, but I jumped them because of the 100% cpu.

After having the 100% cpu usage bug with 11.7 and 11.8 using poclbm/GUIMiner, the 11.9rc fixed that for me and gives a miniscule bump in performance with my HD6870. It's available at Guru3D.
