2) Here is one binary, compiled on Fedora 17, for 64bits and '''only 64bits'''
   wget <nowiki>http://alpha.amahi.org/tmp/hdactl-4.2.1-1.x86_64.rpm</nowiki>
   rpm -Uvh hdactl-4.2.1-1.x86_64.rpm
   # this should give you exactly TWO errors with missing dependencies: hda-greyhole and hda-platform  (if not, let us know!)
3) In addition, here is the _binary_ for hda-platform, also compiled on Fedora 17, for 64bits and '''only 64bits, even though it's a noarch rpm'''. (This is a temporary work-around.)
  wget <nowiki>http://alpha.amahi.org/tmp/hda-platform-6.2.1-1.noarch.rpm</nowiki>
  rpm -Uvh hda-platform-6.2.1-1.noarch.rpm
  # this should give you exactly ONE error with missing dependencies: hda-greyhole (if not, let us know!)
