distcc's a good way to speed up compilation. Another way is to do it purly on the desktop and rsync with the tablet.

Download a stage 3 tarball and extract it to a new chroot location, put the results of those commands into your C(XX)FLAGS in your make.conf, chroot, and start building your tablet system on the desktop as you normally would. When your done building everything, boot the tablet off a USB stick or something and rsync with the chroot on the desktop.
