I think it's just most likely to happen with them, maybe because one
tends to use them differently than other keys.

Maybe it's actually an arrow key in combination with a modifier or the fn
key in those cases? Anyway, the fact that VT switching clears it might
point towards a software problem, unless the keyboard hardware gets
reinitialized at that point.

I've seen that, too.

I'm pretty sure it used to happen for me with 2.4 as well. If anything,
it used to be worse, but I don't remember whether it became better when
going from 2.4 to 2.6 or at what point. The only other idea I seem to
remember is that it could have been introduced when the 2.4 kernel
switched to the new input layer for PowerMacs, in which case it could be
a bug in there.
