:-). That's the intention indeed behind the above game.
Please look at IDE patch nr 105. There is a change to the IDE parts to
include hdparm.h explicitely. The next change will be to let them

declarations of the ioctl stuff will with the two structures will
remain. At this point I will throw the double underscores in front of
the uXX-es to suite you.
