FYI, based on a post I saw about someone getting 2.9 to work with 2011 Manila by cooking it in, I tried it and it DOES work.
I took the maxmanila 2.9 cab file and converted it to an EXT using a cab to EXT converter found over at XDA

Then I dropped into Calkulin's 1.5 b3 kitchen and built a 2011 ROM using a 28223 SYS and it seems to work great. EVERYTHING seems to work
**EDIT**
Looks like NRG will have it in his next build.
