Hello, thank you for taking the time to commit this diff.

Indeed, it only applies to ukbd(4) powerbooks. I have been forced
to move back to an ibook g4 as my powerbook died, and hopefully
I'll find the time soon to investigate the annoyance you describe
with akbd(4) there.

In fact, I sent another diff recently to enforce that the fn keys
act as fn keys and not as special (volume, brightness, etc) keys
by default (without holding fn).

I don't really expect that diff to be commited, just wanted to
remind you.

Finally, I am not sure if this keypad mechanism would be desirable
on other machines besides macppc g4 laptops, as I have seen this
too on other (x86, amd64) computers. I only use macppc these days
so I don't know really, but would be open to extend it if somebody
is interested.

All the best
