But from what I read, it's currently not possible for 32-bit powerpc to
wire up the already present sync_file_range system call.

32bit native is fine (as the ABI in user mode is the same as that in the
kernel).  For 32bit on a 64bit kernel you need the arch specific comapt
routine that I used in the patch I posteda little while ago,
