Well, I'm not sure since you are kind of creating a local mirror, it
sounds like... and Subversion is not a distributed version control
system.  However, if you want to have full distributed VCS features,
you can do what I do and use the Bazaar VCS (bzr) with the 'bzr-svn'
plugin, which allows seamless access to svn branches as if they
were bzr branches.  And then you can use bzr (which is a DVCS like git
or hg) to make local branches and merge changes back and forth between
your branch and the bzr-svn branch which is the upstream GRUB.
It's really easy, all I had to do was install bzr, the bzr-svn plugin,
and then do:

  bzr branch svn://svn.savannah.gnu.org/grub/trunk/grub2

and that created a local 'grub2' branch with full history from the svn
branch.  (This takes quite a while the first time.  But bzr-svn caches
all the history data in ~/.bazaar/svn-cache so it only has to do the
full download once.

Anyway, that's one solution that works great if you want distributed
version control features.  Otherwise, I'll let someone with more recent
svn experience help you (I haven't used svn myself for the past 2 years
since I discovered bzr...).

Colin
