Facililtate automatic loading of the kernel module on openSUSE
depmod scans the devname aliases and populates
/lib/modules/X/modules.devname if there is also a
{block,char}-major-* alias. udev uses this file then to prepopulate
/dev so that a program can open a device node and thereby trigger
autoloading.
This patch adds the devname (requirement 1), and assigns
a static number (requirement 2, for openSUSE only).
