As I covered before. With gentoo, it's easy: emerge -u crossdev crossdev -s1 -t x86_64 (It should be noted that crossdev might attempt to install a hard-masked or profile-masked cross compiler [because of some minor limitations...], so you might want to fiddle with the versions...) That gets you enough to compile the kernel. If you want a full toolchain you can change the stage to 4: crossdev -s4 -t x86_64 If you need a debugger, add --ex-gdb. If you need fortran and other languages, support add --ex-gcc. > Just reinstall. Do it in a chroot while the system is running.

Then, once you are in that 64-bit kernel you should be able to move you userland to 64-bit without bringing down the system. A chroot install might be easier, though, if you have the space available. Reboots are for hardware upgrades, not software. :P I just need to figure out how to use /proc/kmem to move to a new kernel w/o rebooting.
