Today I have successfully applied patch on 2.6.22-rc5. Download patch
from this post:
http://article.gmane.org/gmane.linux.drivers.hdaps.devel/993

Then just modprobe hdaps module (not the one from kernel sources) and
hdapsd should work.

You have to set the unload method manually if you get problem described
in http://www.thinkwiki.org/wiki/Problem_with_APS_harddisk_parking
 echo unload > /sys/block/sda/queue/protect_method

However, hdaps itself (not only hdapsd) has many wakeups and this has
some impact on power consumption.  Has anyone successfully lowered it?
Or is there any solution?
