  R started exporting a lot fewer functions from base packages
(i.e., making them easily/publicly available).  You can use
getAnywhere() to find out where a hidden method lives, if you don't
know, but in this case I think

nlme:::summary.lmList 

should work.  (For everyday use you shouldn't need to dig out
hidden functions with ::: -- if you have an object of class 'lmList',
then summary(object) should just work.)
