Why not just spread Aquaseal  - thinly - over the abraded area.  In my
experience, Aquaseal is pretty tough once it cures, and should help
reinforce the surface of the drysuit against further abrasion.  The key is
to spread it thinly enough so that there is no stress riser between
uncoated and coated fabric.  This can be done by putting a small dab of
Aquaseal on the abraded area, and then using a popsicle stick (or something
similar) to spread it *thinly* over the abraded area, being especially
careful to thin it out to almost nothingness at the edges.  This would make
the adding of any patching material unnecessary.  

Sewing a patch through a drysuit that isn't leaking amounts to creating a
potential problem where none (yet) exists.

Of course, it would still be good to check with the manufacturer of the
drysuit to see what they recommend for repairing an abrasion.
