Yes thats what I figured. I just reflashed the 1.3 PR Kernel (which is default omap) and then went back to Kernel Power and Community CSSU.
I did not flash the whole device so I did not loose MyDocs etc.
Flashing a thumb Kernel directly (if possible) would also probably reset the rootfs, so before messing I figured using the tried and reliable way is less likely to brick my phone.

I will "upgrade" to thumb again when everything is back to "normal"
