Well... you'd have to delete the repository (or rename it or move it
out of the way for backup purposes) and create a new empty one
between those two steps:
$ svnadmin dump --revision 1:90 [path-to-repo] > partial.dump
$ mv [path-to-repo] [path-to-repo-backup]
$ svnadimn create [path-to-repo]
$ svnadmin load [path-to-repo] < partial.dump
Other than that, yes, I believe that will work. Anyone who has a
working copy of any revision higher than 90 will have to trash it and
check out a new one. (If they don't, things will probably break in
horrible ways.)

As above, move the old repo out of the way, then create a new empty
one, after you create the dumps, before you try to load the dumps
back in.
Note that your revisions will get renumbered when they're loaded back
in. Whether this is a problem for you depends on how you've used your
repository. For example, if you've written lots of commit messages
like "Merged revision 5 of foobranch into trunk" then those comments
will no longer be accurate because the revision number will have
changed in the new repo.
There may be a way to avoid most of this problem but I'm not sure
because I haven't had to use svndumpfilter myself. Maybe someone else
has some better advice.
