Dual Opterons don't see all memory

[Aryeh Friedman]

I have the same problem on a intel duo x6850 what options/flags do I
need to set in /usr/src/Makefile and/or /usr/src/sys/i386/conf/GENERIC
to make it compile 64 bit not 32?

--Aryeh

PS I think some of the nvidia issues I have posted might be due to this
