Sapphire 1.0.0, a superlative custom ROM for the Motorola Droid, was just released. You can upgrade to it via ROM Manager using the steps I previously wrote. Just substitute build 1.0.0 for 0.8.4. You still have to downgrade to ClockworkMod 2.0.1.3 to update using ROM Manager (i.e. ClockworkMod 2.5.0.1. won’t reboot your phone when installing this rom).

I just upgraded (I wiped cache and data, just to be sure), and so far things are working very well.
