As far as I know, the WMS driver does not support TMS. (I said on the
MapServer mailing list the other day that it did, then realized that I
think I'm mistaken.)
That said, it's not entirely clear to me how different a TMS driver and
the WMS driver really are: I had looked at the code and felt like a TMS
'minidriver' for the WMS 'driver' wouldn't be that difficult (but beyond
my coding skills): however, I can also see that a TMS driver can have
significantly more features in the realm of reading local files, so I
don't know how much of the code would end up making sense between the
