Well, in all cases, the wrapper which invokes the X server is setuid root.
It oughtn't matter what the group/other permissions are, as long as
/dev/fb* are owned by root.  Then again, I haven't done any experimentation
in this respect - I didn't actually have to change the permissions.

Nothing actually explicitly refers to /dev/mouse unless you tell it to, I
think, although I believe many things default to it.

The reason (as I understand it) is that on Intel boxes there are a whole
pile of different mouse devices - various kinds of bus mouse plus serial
mice - so /dev/mouse evolved as a convenience.  Most useful when the
installer asks you "What kind of mouse do you have?" and automagically
configures the link for you.

On Suns, though, there is only one kind (I think - maybe the PCI keyboard/
mouse stuff does things differently?), which is /dev/sunmouse.  If that's
the only mouse device, then perhaps the base ought to contain the
/dev/mouse -> /dev/sunmouse symlink.
