Well, Mandriva still has enough static dev entries to give you /dev/null and
/dev/console, which gets you through early boot ok without an initrd. I
think a lot of other distros are still in that state as well, and haven't
completely removed everything in /dev

Harry was talking about that on IRC today actually, so I'll leave it in his

Yeh, that what's I was hoping to get out of all of this. The net effect of
adding those drivers in is a few 10s of k of object code, but just helps
with the out of the box experience for people that were using the -xen0
kernel.
