OK. I used the RUU and wiped back to stock. Rooted, then applied this ROM.
Initially it FC'd for the google apps (which I figured it would...maps in in /data in this build). After pulling maps out, then reinstalling/rebooting all is well.
For grins, I then RUU'd back to stock and tried the unoffical Modaco 1.3. Same result. Not unexpected, as the build prop and update scripts between them are almost alike...we both built on Paul's work.
The only thing I can think of, is there is an issue with your SD card. Try flashing and remove the sd card, then reboot. Some users had the same issue with the original Modaco CDMA rom, so it's worth a shot. If that works, reinstall the card and restore your backup, and let me know. We can then see what we can do from there.
