JMZ and I have beta Manila 2.5 which has been ported to VGA by muttim86. It still needs work, but is functional. I should have a CDMA Diamond stripped down alpha rom with it posted at ED/TP tonight, and JMZ will have for CDMA TP soon.
EDIT:
The only CDMA Diamond ROM with Manila 2.5 is here now, with screenshots:
