Modem device is owned by root, so my user can't access it.

Thanks for that.  I'm sure it is the right track;  my mileage did vary, I'm 
afraid.

I tried the suggested line in /etc/udev/udev.rules as this appears to be 
the appropriate
file, but it made no difference, even after the command 'udev restart' or 
an actual reboot.

Did I put the line in the right file?  Some of the howto information that I 
looked at suggested
that the order of commands matters;  if your local rules are read after the 
default ones
then they don't get applied and the defaults stand.  Could that be 
happening here?  I didn't
see any references to default (modem) setups in the file I tried editing - 
was it already set
somewhere else?

Also, I haven't gone into the rule syntax properly;  I'm particularly 
suspicious of assuming
that KERNEL="536ep0" is correct.  536ep0 *is* the device name that the 
system is using
by default, but the kernel module is Intel536.ko (IIRC).

So I'm further forward, but still at the questions rather than answers 
stage for now.

PS  The good news is that the Modem Monitor panel applet *does* work with 
the default
permissions for /dev/536ep0, so the user can dial out.  It's just that 
gnome-ppp offers
a preferable interface in my opinion.
