No, I don't think so. RM is being a bit flaky for me, too. Yesterday I tried to flash the Chevy kernel I had running last week with this same ROM clock and it rebooted while in ClockworkMod Recovery 6 times. (-A reboot in Recovery always makes me nervous.) It does this when I select "install update.zip from sd" but not once I'm in the Nandroid file to do a recovery or backup. I was probably in Recovery a total of about 12 times.
After the installation was finally successful, it wouldn't stop boot looping no matter what I tried. Then when I went back into Recovery manually to restore my latest backup, it decided it didn't like my sd card. I finally gave up on trying to install the Chevy kernel. I have a P3 in that OCs to 1.25GHz, but it's a battery whore so I'm going to have to curb it through SetCPU.
