I tried advancing the ssh startup script from S21 to S22 (past the nfs
stuff and way past the udev stuff), but that didn't help. It looks to
me like /dev/pts is definitely created and mounted prior to ssh being
launched.

I can see I'm way over my head on this udev problem. Without some more
specific instructions on how to fix it I guess I'll have to chalk it
up to being "not ready for prime time" and go back to the 2.4 kernel.
I've spent the better part of the last three days on this and I'm not
much closer than I was when I started. If I can't SSH into the box I
can't use it. I don't understand how the tarballs on the 2.6 page at
TS could work for anyone though without modification. The sarge-udev
root file system can't work with SSH as is. 

Thanks for all your help anyway.
