After some more research, I figured that although the project home page -
http://user-mode-linux.sourceforge.net/
mentions that kernels after the 2.6.9 support UML, the vanilla 2.6.10
did not have it until I had patched it with the right patch from -
http://www.user-mode-linux.org/~blaisorblade/

Now that I have compiled that, is my doubt- 
How do I get a ext3 root_fs running? I am asking this because the
suggested root_fs builder
http://umlbuilder.sourceforge.net/
does not list a new distro like FC3 that I am using and it doesn't
look like having support for ext3. And the pristine root_fs they have
is for RH7.2

How? Supposing I have ext3 root_fs running, I copy my modified ext3 to
the ../fs. directory in UML and compile another kernel in UML?

I just checked out QEMU and from the first look it seemed like vserver or Xen.

Thanks!
