Possibly. I'm not sure about mount, but unless my eyes have gotten
*really* bad, I see the 'not supported by kernel' thing every time I
try to start pppd as a regular user. Gave me a heart attack the first
few times. And I'm fairly sure I've seen it with mount also. I'm not
positive I guessed right, but I'm also not making this up.

It occurs to me the reason for the misleading error message might be
because when a regular user tries to do X, but X requires a
module, the module doesn't get loaded and, for whatever reason (on
RedHat -- score 1 [more] for TurboLinux) the 'not supported' message
gets through to the user and the 'no permission' message doesn't.

In any case it would be pretty strange for a standard RedHat
installation not to have iso9660 support. Not impossible, I'm sure,
but strange.
