     Can't help you with the modem noise issue, but the fast user 
switching "rotation" effect, Mac OS X 10.3 Help says in response to a 
query about "fast user switching and rotation,

     Your machine is a G4 "Digital Audio," and can have a number of 
different AGP video cards. I suspect it has the ATI Rage 128 Pro, 
since ATI claims Quartz Extreme works on all Radeon cards. Don't know 
about Nvidia cards; their Website is not terribly forthcoming on the 
subject. The Apple "tech specs" page for Panther says "NVIDIA 
GeForce2 MX, GeForce3, GeForce4 MX, or GeForce4 Ti; any ATI AGP 
RADEON card. A minimum of 16MB VRAM required." for QE support.

     HTH,
