I mean device numbers to modules, not devices themselves.
I created /dev/afa0 manually basing on /proc/devices.


Let's use the source...
In case of aacraid it's (linux/drivers/scsi/aacraid/linit.c):

        aac_cfg_major = register_chrdev( 0, "aac", &aac_cfg_fops);

and (in register_chrdev(), linux/fs/char_dev.c) major==0 means last
unused char major less than 255.
