That will have to be a separate project.  From what someone here told me
other OS's (Linux, Windoze) still use 4K block drives in 512 byte block
emulation mode.  Can anyone verify/refute this?

Also, most VMS IO on itanics is through SAN storage servers, and they
are the ones that have to directly deal with 4K blocks.  I don't know
if storage servers themselves present themselves as using 4K blocks.

Of course there are directly attached SCSI drives that could benefit,
plus x86 is a different beast.
