Guys,
I am attempting a conversion myself, and am understandingly interested.  
Couple of questions if I may.

Seth,
Let me see if I follow you.
1) Install into a partition I can chroot into.  OK.  Is this to be a 
temporary 
install only to chroot into and build a pure 64bit kernel?
2) Copy kernel into my /boot so I can boot into the 64/32 bit kernel.  Are 
you 
saying that I can boot into the 64/32 bit kernel using my 32bit "root 
partition", and then can chroot into the install partition from step 1) 
above?
3) If the answer is yes to  above I can now build a pure 64bit kernel
4) Since the first install was temporary I install the iso again to a 
permanant partition which will be a pure 64bit bootstrap system.  Is sorcery 
and a codex installed?

Daniel,
You say do what Seth recommends but start from the distribution:
 
http://distro.ibiblio.org/pub/linux/distributions/sourcemage/mirror/smgl-x86_64.tar.bz2.

That distribution doesn't applear to have a kernel.  Are you saying to use 
the 
iso for steps 1,2,3) above and the distribution for step 4) to get a 
bootstrap system?

Thanks,
John
