Could you please read my previous e-mail again.
1. I don't ask coreboot people to solve this issue. It is obviously different project, so it would be stupid to ask this. 
2. The thing I'm asking
   a. Status of 64bit support. I don't know if coreboot is tested in configurations when 64bit PCI devices occupy high memory on Win2003 or WinXP. 
   b. Ideas - in lucky case.
That is.
