OK, so I took a minute, double checked the fstab inside the 32-bit
system, made a few changes, and then set up a specific boot option in
grub to be able to do this. It worked, but booted a 64-bit kernel. My
problem right now is that the 32-bit area is trying to build a 64-bit
kernel. Here are the two /etc/make.conf files:

lightning ~ # cat /etc/make.conf
# These settings were set by the catalyst build script that
automatically built this stage
CFLAGS="-march=k8 -O2 -pipe"
CHOST="x86_64-pc-linux-gnu"

CFLAGS="-O2 -march=athlon-xp -msse2 -pipe -fomit-frame-pointer"
CHOST="i686-pc-linux-gnu"
CXXFLAGS="${CFLAGS}"
MAKEOPTS="-j2"
PORTDIR_OVERLAY=/usr/local/portage
lightning ~ #

What would I need to do to get the 32-bit area to build a 32-bit
kernel? When I run make menuconfig and try to change the processor I'm
only given 2 64-bit options.

thanks,
Mark
