Thanks for pursuing this.
Unfortunately, that is too risky.  statvfs is the preferred
interface, and other systems have both.

Since Tru64 UNIX 5.1 is not exactly mainstream, and the goal
here is to work around their statvfs bug, I'm willing to add to
this exclusion list in fsusage.m4:

  #if defined __GLIBC__ && !defined __BEOS__
  Do not use statvfs on systems with GNU libc, because that function stats
  all preceding entries in /proc/mounts, and that makes df hang if even
  one of the corresponding file systems is hard-mounted, but not available.
  statvfs in GNU libc on BeOS operates differently: it only makes a system
  call.
  #endif

E.g., add these lines after that block:

  #ifdef TRU64
  "Do not use Tru64's statvfs implementation"
  #endif

Does that solve the problem for you?
