This string becomes the name of a directory in sysfs. Having a ' '
character in a directory name just doesn't seem like a good idea; at
the very least it's likely to confuse shell scripts. (A ':' character
is a lot less subject to misinterpretation.) I could change the '-' to
':' if you prefer.

Thanks. I'll separate out the driver name change from the rest of the
patch.
There are a couple of questions remaining. The patch enables wakeup on
the i8042-aux device -- is this a good idea? I haven't tested that
part of it yet, but we wouldn't want suspended systems waking up just
because somebody moves the mouse around. On the other hand, on some
machines (like mine!) it may not be possible to enable keyboard-wakeup
without also enabling mouse-wakeup, since they use the same GPE.
Also, the patch effectively tells the kernel that ISAPNP and PNPBIOS
devices are incapable of issuing wakeup requests. Is that going to
cause trouble for people? Would it be better to change the patch so
that it doesn't call device_set_wakeup_capable() if
dev->protocol->can_wakeup isn't defined?
