The 32bit kernel should support up to 4GB physical memory (we use 32bit physical address). More than 4GB is not still supported in 64 bit either. I am working on adding 64-bit page table entries, which will add this part. The only advantage on 64bit now is that we use XKPHYS to access memory above 512MB. > 3) No Geode support.

I still haven't really tested the 64bit, so any reports will be useful JC.
