The following patches do two things. First they add support for the
A1020 5.25" drive (tested, and it works.... well, it suffers the same
problems as 3.5" drives, but is no worse). 

Second, it provides partition information that is more correct.  It now
fills in the rpm value.  It is currently incorrect (someone please fix),
but at least it prevents the "warning! zero revolutions/minute" message. 

I also changed the reported pack name from "some pack" to the
size/format of the disk...  that's at least marginally more useful
information. :-)
