If that does not solve the problem (try it first), you might want to ask
your question on <spi-devel-general@lists.sourceforge.net>.  There are a
number of people there that have used spidev, and even the original
author, Andrea Paterniani <a.paterniani@swapp-eng.it>, is active there.

They would be if udev (or even mdev) were in use.

The sysfs class nodes have a "dev" file with the major
and minor numbers to use with "mknod".
