hdparm's init script iterates through /dev/ide|/dev/discs to set parameters to discs via hdparm using e.g. 'all_args="-d1 -c 3 -S 60"' in /etc/conf.d/hdparm After udev has dropped devfs mappings in /dev/ide and /dev/discs (not LSB) this behaviour misses some devices. Even when setting 'hdX_args=...' with X = {a,b,c,....} the init script checks for an existing symlink in /dev/ide or /dev/disks before executing hdparm on that disk - an thus misses this drive. See also: http://thread.gmane.org/gmane.linux.gentoo.devel/36093 for a mode complete description.
the code already supports non-devfs schemes ... it'll just default to devfs style if devfs nodes are provided updated the check to see if both /dev/.devfs and /dev/ide exist
