timeout(9). However, we are eventually going to start requiring drivers to
not use Giant either (and retiring timeout(9) is a step in that direction).
Also, most of these drivers are for ancient hardware. scd(4) is support for
a relatively rare pre-ATA CD controller. The much-more common matcd(4) driver
(which is the driver used by my old SoundBlaster 16 card that provided a CD
controller (not just sound, but data as well)) was removed back in 2002.
