You should be able to get away with not using a livecd: you don't
really need to chroot to get an initial Gentoo system working,
*especially if you have console access*.

Some pointers:
- Unpack your stage tarball.
- Build the kernel and initramfs on an existing Gentoo system and copy
them over.
- Add the gentoo kernel and initramfs to menu.lst.
- Clear out the root password in /etc/shadow.
- Reboot the box.

You can then log in as root on the console, configure networking, and
run from there.
