You may want to run it on the stock kernel first. Plenty of users here have reported good results with the stock kernel. If you're itching to flash a new kernel there are plenty of choices over at the Rootzwiki development thread. I've been running various versions of Lean Kernel the past couple of weeks with good results.
Have you tested it out with other kernels?
I use lean kernel. It works great. Franco's is nice but messed with my media player
