hppa locore diff

This diff is needed to support the lcd display on the four-digit
B/C/J-class hppa workstations.  However, since this might break other
systems, I'd appreciate it if people can give it a try on their
PA-RISC 2.0 systems.  There's no need to test this on (older) PA-RISC
1.1 systems, since this code doesn't get executed on those.

Thanks,

Mark
