This has been done on purpose. I knew that you would appreciate. The
problem is probably present with the other cards but since I could not
validate or test the patch with them, I have left them unchanged. If you
were to determine that it apply to all of them then maybe the patch
could be moved to ps.c to wrap hw_init() call.

done. I am about to resend the patch splitted into 2 commits.
