I'm working on a lfn driver using direct disk access that supports
fat32.  It's not yet ready for even a beta release, but it should be
ready sometime in the next few weeks.

Implemented or planned features:
- case sensitive (optional)
- short names generated by 48 bit crc of long name using 6 bit encoding
and extended ascii
- will not match against the sfn if the file has a lfn (optional)
- fat12, fat16 and fat32 support.
- should run on any dos version (2.x up, but only tested on ms 6.2,7.1
and od 7.01)
