No, that's not the problem. The system was specifically whining about
device major 10, minor 134 (which is the apm_bios device under the V2.4
kernel). Since nvidia's module does link in with apm (advanced power
management) to blank the screen and such, I suspect that's what
happened. As to the major device 195, that is the major device number
assigned to nvidia and should be created on-the-fly when X fires up the
nvidia module.

Don't thank me until we solve this! :-)
