| If you run 'make-kpkg kernel-image' (with correct flags), a .deb file
| for the kernel built by the current source is created. Nothing in
| your current running system is touched at all. You can then use your
| favorite method (e.g. scp) to copy the .deb file over to the slower
| machine, and run, as root, something along the lines of
| 'dpkg --install kernel-image-2.4.18_2.4.18.donut.1_i386.deb'
I've done this, and it works great! Even modules are handled right.
The only trick is to select all the right kernel options (eg included
fp emulation for that 486sx) and don't optimize for a newer subarch
than the old machine is.

You can keep the config files separate and just replace the one in the
source tree. You only need 1 source tree.

True. I wish I could build in 5 minutes! It takes around 20 on my
good box. (I've never tried to measure how many days my old box would
take assuming it wouldn't die from lack of memory first)

Windows, hmmm, does it come with a GUI interface that works or just
pretty blue screens?
