Hi all,

I've installed my current system by debootstrap'ing in a new 
partition/lvm logical volume.  You only need to run an x86_64 kernel (of 
course with 32-bit emulation enabled):

	# apt-get install kernel-image-2.6-amd64-k8

Reboot and boot the new kernel, then run

	# debootstrap --arch x86_64 {sarge,sid} $mountpoint $mirror

You'll need to copy some files over (like 
/etc/{fstab,hostname,hosts,...}, whichever you need.

Good luck,

David
