SubjectRe: Any limitations on bigmem usage?
Thanks to all that replied.  I've never needed to use so much memory before, and 
was ignorant to how much magic was implemented in the 64G support on IA32.
Unfortunately, there's not quite enough magic in there for my needs... now to
find an affordable SMP Alpha system....

Thanks again,

-Matt
