4 You mean run a 64-bit kernel with 32-bit support. There's no such thing as a
5 32-bit kernel with 64-bit support (at least not in x86-land).

10 No, it won't, but it's a little bit tricky to set up. You'll want to use an
11 i686 stage3, and set ARCH to x86 or ~x86. Then, you'll have to install a
12 cross compiler (and binutils, IIRC) and cross-compile your kernel.

14 You could always just use a 32-bit kernel. Do you have 3G or more RAM or need
15 to run 64-bit programs?
