> What's a "major/minor device number"?

The short answer is that it is simply an index into a kernel table
filled with driver (function) entry points.  A call to
open("/dev/somedev",..) will execute this code to prep the device. 
Likewise the minor number usually indexes a data structure for a
specific instance of a device.
