That page is old, as I noted in my other comment, and if you read the Constitution (article 3) which governs the Hugo award, the nomination is not so numeric; for example:

Except as provided below, the final Award ballots shall list in each category the five eligible nominees receiving the most nominations. If there is a tie including fifth place, all the tied eligible nominees shall be listed.

and

3.8.5: No nominee shall appear on the final Award bnominatallot if it received fewer nominations than five percent (5%) of the number of ballots listing one or more nominations in that category, except that the first three eligible nominees, including any ties, shall always be listed.

Going back to the 2011 data (and being mindful the vote counts have set records frequently in the 2000s as the convention apparently grows), we see the last place novel is 306 ballots. pg17 gives us the original nomination votes: last place novel there was 78 ballots.

So, yes, MoR could probably get on the ballot if >78 people all remember to register by 31 January of that year (good thing MoR isn't finished yet because it's too late for 2012) so they are eligible to vote on nominations, and actually put MoR #1 on their ballots; see the Constitution again:

Each member of either the administering or the immediately preceding Worldcon as of January 31 of the current calendar year shall be allowed to make up to five (5) equally weighted nominations in every category.
