Are you using 3D desktop effects, and did you previously use the
proprietary nvidia driver? If so, have you rebuilt it for this kernel
If that's not the problem:

Please get a performance log and send it to this bug report:
1. Install linux-tools-2.6
2. Run 'perf record -p $(pidof konsole)'. This will create a file
3. Open a new tab in konsole
4. Kill the 'perf' command by pressing Control-C
5. Send the file 'perf.data'
Once a job is fouled up, anything done to improve it makes it worse.
