I have a horrible hack to the twe driver to enable it to understand the
32 bit binary ioctl's.  It was enough for me to run the CLI.

I was thinking about committing it, but I've been meaning to ask the
3ware folks for a native build, which would be much better.  Maybe they
do a build so I won't have to commit this.  I've given this diff to all the people
that have asked.

Their management stuff generally passes opaque data blobs through 
from the cli/3dm to the firmware.  We don't need to see what it is.

Anyway, the diff:
