I just now found out about this. Apparently it has been out since last December. Pre-alpha ICS ROM on the Droid 1:
[ROM][Pre-Pre-ALPHA] Droid A855 ICS Build Attempt - Page 159 - xda-developers
I installed it on mine, and it is pretty sweet. Camera app runs but crashes when you take a picture. Otherwise it seems to work fine. Wifi works, Maps work great on it.
