do you mean there is a way to "pre-load" kernel modules now ?
I think GRUB allows loading of modules via multiboot specification,
but does Linux complies to this spec ?

in my diskless setup, I use a /mnt/writable ramdisk created
at boot time in init scripts, and I have a farm of symlinks
for /tmp /var/log ... pointing to /mnt/writable/* . could
you explain how your ramfs solution works ?

by the way, it looks like the only thing preventing / to be
mounted read-only is /etc/mtab, which could be symlinked to 
/proc/mounts. does anybody have any pro/con comments about that?

and it is not practicable in cross-platforms setup, i.e. when
the NFS server is a PC and the client a Macintosh. looks like
there are two "solutions" : either netboot a client with write
access to do apt-thingies, either a "dpkg --root /images/foo",
with tons of tricks to fool postconf scripts ...
