You can make your own handy enough. Get a working .config from a normal
kernel install complete with NFs modules and do the following

make oldconfig ARCH=um
make linux ARCH=um
make modules ARCH=um
mount root_fs ~/mnt -o loop
make modules_install INSTALL_MOD_PATH=~/mnt
umount ~/mnt
./linux

and load the NFS modules and you're flying it. If you haven't compiled
your own kernel before, you'll need to start there but the questions asked
for UML aren't particularly hard and help is available. Just run make
config ARCH=um and go through them one at a time. It'll take a while but
you'll get there. If menus are your thing

make menuconfig ARCH=um
make oxconfig ARCH=um

are your friends. Personally I find been asked the questions with make
config easier, but thats just me.

I seriously doubt it will be. You need the NFS kernel modules and
compiling your own kernel is the only way to do it. A normal linux module
will not work in UML.

Nice thing with UML, if you get the kernel compile wrong, it doesn't
matter. There isn't anything serious to break ;-)
