Keita,
We have not provided supported library routines for this since we've found that actual ASCII file formats often require slightly different readers. And thus we could not provide robust readers. Instead we have some example routines in src/mat/examples/tutorials/, specifically ex78.c that the user may modify for their exact needs.
I've added this information to our FAQ.

Since there is a huge collection of sparse matrices at University of Florida, such routine is very useful for benchmarking KSP and PC. Thanks, ================================
