I have enabled JIT on two previous ROMs (maybe more?), and the outcome is always the same. At first, it's really fast! But as time goes on, I began experiencing random reboots and strange behavior. All went away when I would disable JIT. So, you can count me out. BTDT I am running the 1.3G kernel and this is the fastest my DROID has ever been, so I'm satisfied without JIT.
