Can't get Voodoo 3 to work

[Matheson]

Hey,   I've been working on getting my Voodoo 3 3000 AGP to work, but I can't seem to.  I've compiled the 3dfx module, but when I try to insmod it, it gives me the error:   3dfx: Could not set MTRR for Voodoo card   I've made the device, and set the permissions, so I'm not sure what else to do.   Cameron Matheson
