bitkeeper revision 1.46.1.1 (3e4ea2f52nebi38hIZkpYvqaZogL3g)

Allow root to be other than nfs - remove the nfsroot component of the 
xen command line, and add "ro root=/dev/xhdaN" to the *module* command
line. E.g. 
kernel (nd)/usr/groups/srgboot/moonraider/image.gz ipbase=128.232.35.190 gateway=128.232.32.1 netmask=255.255.240.0 dom0_mem=262144
module (nd)/usr/groups/srgboot/moonraider/xenolinux.gz ro root=/dev/xhda7
