/*
* This should work in theory but I haven't tested it. Anyone
* on a BSD system want to test this for me? In the meantime,
* binary search mechanism should work just fine.
* This code works for FreeBSD 4.11 i386, except for the full device
* (such as /dev/ad0). It doesn't work properly for newer FreeBSD
* though. FreeBSD >= 5.0 should be covered by the DIOCGMEDIASIZE
* above however.
*
* Note that FreeBSD >= 4.0 has disk devices as unbuffered (raw,
* character) devices, so we need to check for S_ISCHR, too.
