Is there a listing that identifies the hardware to the major
minor numbers that a person could keep as a reference? Is
it in a updated listing on the web somewhere as the hardware
that the kernel supports increases? I've never looked at
the kernel source, so is it in there where I could access it
for any given kernel version? Thanks,
Dow
