I thought I read in the Roundel that Bridgestone (at least) says you can patch their run flats. A quick google turned up this:
------------------
Bridgestone and BMW both agree that these runflat tires can be repaired
as long as they meet specific criteria and the repair is performed
properly.
A proper repair requires the dealer/tire shop to remove the tire from
the wheel to perform an inspection inside and out. Then the repair must
consist of both a plug to fill the hole, preventing water and other
debris from getting into the tire, and a patch on the inside to reseal
the air chamber. If your repair was done in this manner, the tire
should perform acceptably within posted speed limits.

I don't have run flats anymore, but I'm sure there is more definitive information out there.
