I recently changed the implementation of getpagesize() to use the
information passed by the kernel in auxvec, when I added code to use
auxvec for other reasons.

This works fine for me (apart from the fact that sys/user.h does not
exist for dietlibc and PAGE_SIZE is defined in sys/shm.h).

What environment are you using this program in?
x86?  Inside user mode linux?  What kernel version?
