The problem is, it all depends on what the drivers report the
sector size as.  What happens if the BIOS/Windows/Linux don't agree?

Recipe for disaster IMHO.  We've already been through this pain with
CHS crap.

Intel should add a sector_size field to the header, if they are
serious about this sector_size idea (which seems a bit crazy to
mean anyway, but...)
