Stock FP1 kernel Odin: http://www.mediafire.com/?ns38atiw1d7er5x
EDIT: We now have a CWM version thanks to dwitherell. See his post here: http://forum.xda-developers.com/show...84&postcount=8
Make sure you're at rfs before flashing either of these kernels, otherwise, you'll hang at boot.
DISCLAIMER: As usual, I'm not responsible if this breaks your phone, burns down your house, or causes your dog to run away. I've tested it and it works for me.
Big thanks go to imnuts, both as an inspiration and for the many examples that I've studied and followed to get enough confidence to do this.
One more note. When I was testing this, installing PBJ over FP1 killed my boot animation and flashing the FP1 kernel didn't bring it back. If this happens to you, reflash your ROM and it should fix it.
