I just pulled a version of lpt I had done in the `magnum' branch and put
it in -current.  This version combines the functionality of lpa, and
should be a bit faster and deal with some errors better.

In this version, a bit in the minor device number selects whether it is
polled or interrupt-driven.  If you omit the IRQ specification in your
kernel config, you will only be able to open the polled device (named
`lpa' for historical reasons).

Regardless, you will need to remake any `lpa' devices in /dev with the
latest MAKEDEV script, and change any `lpa' devices in your kernel
config to `lpt'.
