You can try go to settings > manage apps > all

go to those apps which gives your FC and choose force close and clear data then reboot your phone

@hardcore and supercurio mentioned to me that it will depend on samsung on the source codes. Looking at the trend, the last release was for JPM and then no more, JPO/JPA was based on JPM as well.
And with JPU as a totally different breed, recompilation of the kernel is impossible, and except configuration tweaking and tuning, nothing major can be improved at the kernel level. So far, none of the existing kernel without filesystem tweaking can beat JPU, JPU kernel is almost perfect, a 50% jump from the JPM-based kernel, not even the mods in XDA can beat that.

i tried doc n darky.n the darky really impressed me!

What steps did you take?
the easiest way i find is to do

1) Flash to any Eclair rom
2) put CWM(name it as update.zip) and Darky's rom in your internal SD
3) boot into recovery
4) apply update.zip
5) apply update.zip again, now will boot into CWM
6) Choose darky's rom
7) and feel happy about it.
