I have not worked with the server side but will be in the coming months.
Maybe someone on the list can help.

  Is there a layoutdriver to modprobe on the client or is it embedded
  in the kernel itself ?

You could build it in but I normally build it as a module.  The startup
script assumes it's a module and probes it:

fedora# grep blocklayoutdriver /etc/init.d/blkmapd
        modprobe -q blocklayoutdriver
fedora#

Right now the nfs-utils rpm doesn't install the startup script.  I'll fix
this but for now just copy it from the source:

cp nfs-utils/utils/blkmapd/etc/initd/initd.redhat /etc/init.d/blkmapd
chmod +x /etc/init.d/blkmapd
