Here is a diff and a new file (hp300/dev/apcireg.h) to provide
support for Apollo keyboards on hp4xx machines in SYS_UBOOT.
This is primarily for Jason's review, but if you have such
a combination I would appreciate any feedback you may have.
Support for these keyboards as the console keyboard is
proceeding; I haven't had any feedback about wscons, so I
will be integrating the Apollo keyboard support into ite.

invites the trivial response "because we define as fundamental those
