I have the impression that many new (PCI/AGP) video cards can work fine without the legacy VGA stuff - therefore, no conflict when using several cards simultaneously. Please avoid unnecessary disabling of such devices, that only causes trouble for those of use trying to use several screens at once. (Possibly with several simultaneous _users_, who don't want their screen disabled for no good reason.) Of course one may have to buy the "right" cards when setting up such a machine. Helge Hafting
