Ok. In which case, a Sybase backend will probably hit the same
problems as the existing MS SQL backend. MS SQL doesn't contain
support for LIMIT/OFFSET in queries, which Django uses these keywords
to optimize the results obtained from large queries. (I think this
problem has been fixed in SQL Server 2005, but don't quote me on that.
I don't keep close tabs on MS SQL).

Thanks for offering to help out on this.

As a guideline - if you are serious about trying to get Sybase (or,
for that matter, any other database) onto the officially supported
list of databases, we will be looking for more than a once-off set of
patches. We will also be looking for a commitment to support the
backend in the long term. This is especially true for databases
without a free license, as the core developers won't have access to
those databases for testing.

The development of the Oracle backend serves as a textbook example of
how to do this. A users group in Boulder, CO has 'adopted' the Oracle
backend. They have spent 6 months getting the code up to scratch, and
have made a long term commitment to keeping it solid.
