[...checking sources...]

_Both_ entries are likely not to work.
Several modules (incl. dm, fbsplash... just grep kernel sources for
MISC_DYNAMIC_MINOR) have minor numbers for (char major 10) assigned
dynamically (in 0..63 range, starting from 63 down to 0).
They are supposed to work by creating device files dynamically using
udev (or devfs, but it's obsolete).

(well, they can be hacked by using some static minor instead of
MISC_DYNAMIC_MINOR, but then such module can fail to load if that minor
is already reserved by other module using MISC_DYNAMIC_MINOR...)
