We bought cheap notebooks to control our custom data acquisition system, which
requires EPP mode (read/write, data/addr).  The bios does not offer EPP mode,
and indeed hardware EPP mode appears not to work, although the parport driver
tries to use it.  EPPSWE mode does work for data r/w and addr write, but addr
read requires this patch.
