OK, so I had another discussion with Michael Karcher who analyzed the bug and the problem is apparently that after the change, mkimage adds an alignment to the module address which it did not before the change. And the suspicion why this affects ia64 and not x86_64 could be that the module data is properly aligned as mkimage expects while it's not on ia64. Adrian -- .''`.
