ok here is a ROM or actually a nandroid backup with JIT enabled, I could not get it to work any other way, when I cooked it into a new ROM it would always give me the bootloop but if restored from a backup i had JIT would work fine. so I had to take the datadata.img from an old backup and add it to a new backup.

this ROM is overclocked at 1.113 with wireless n and may or may not work for you, everything seems to be working fine for me, and if any app FC's on you you may have to uninstall then reinstall it. it has ADW Launcher because launcher pro kept FCing on me and would not work. I am getting around 10.110-10.936 MFLOPS in linpack and quadrant scores of around 700. it is the same ROM as the one above this minus launcher pro.
Intsall:
download the file and extract it and put it in sdcard/clockworkmod/backup
boot into recovery select nandroid/restore and select the correct backup and let it do its thing.
once it restarts it will boot up to the lockscreen but will not run the initial setup program, so you will have to manually configure the settings.
after you restore to this you should not have to clear data or cache when installing one of my ROMs.
