OpenEmbedded is similar to buildroot, so I guess you mean Buildroot and 
not FPGA? I haven't managed to use CVS and GIT directly in Buildroot. I 
was hoping that OE makes it easier to test variation of compiler, 
c-libraries and kernel.

Is the V3 code in GIT? Is that the change to increate the addressable 
memory area? Does it involve major code changes?

Lot's of interesting stuff. You will hear about it soon (finally...)

Unfortunately, I can still only tell you that I work for Rearden Labs.

I would love to. Let me know if and when.
