If that's the case, then it isn't fixed as of yesterday's snapshot.  I
have brought in an ALC268 test board to replace the AD1986a.  I will
know real soon if this is the issue.

This isn't for the OQO, this is for a new Intel platform.  And it will
market with 256M-1G memory.  If that bit is only for 64bit memory
addressing, then I'm not worried about it.  Sorry my earlier mail was
confusing.  I was getting ready for work and wanted to toss a quick
head's up.
