The driver does not disable the vga ports.
You can disable them by disallowing all IO access to the card in PCI 
config (bit 0 of command register). (not related to driver).
Please note that the driver only works on NV3 (Riva128) cards. If you 
want to use it on a newer card, it will need a few changes.
