Patch carried over from the prior iasl package and updated. This allows
for builds on systems requiring aligned memory access. Please see
http://lists.acpica.org/pipermail/devel/2010-July/000159.html. Resolves
BZ#865013 and BZ#856856.
--
Add more platforms to the list of the ones requiring aligned memory access.
Also fix callsites where wrong assumptions where made in terms of aligment.
