   Why do you want to enlarge the buffer cache if you are going to access
   the filesystem through the raw device? The way to do the latter you can
   easily find in the fsck(8) sources. But if you use the raw disk you have
   to manage buffering for yourself and of course in order to keep
   your data in a consistant state, the file system must not be mounted.

 c) How about an mmap(2) aproach? FreeBSD is the OS of choice for that
    purpose.
