This will probably bite you in the ass. Most notably, support for devfs was 
dropped around 2.6.13, so unless you are managing a static /dev, you're going to 
need udev. However, I'm not sure if the baselayout from that long ago had any 
notion of udev or if you can even build udev while running a 2.4 kernel (this is 
probably less of an issue).

Really, the "best" way to do this is to just do a new install on the second 
drive. However, you might have some of the problems noted above, since you're 
still running a 2.4 kernel while building a system intended for 2.6.

I guess that your only remaining "sane" option is to build a new install on a 
"local" machine, and then rsync the entire thing over to the 2nd drive in your 
existing machine. Then setup grub to boot from the install on the 2nd drive by 
default.
