Nope.  It just needs to be running at least a 2.6.2 kernel, so we can 
mount the sysfs filesystem.  We build udev into /tools, and use that 
from inside chroot to create our /dev directory in chroot.  The only 
requirement on the host is the presence of 2.6.2, because not all 
devices were in sysfs prior to that point.
