not a hdparm bug sounds like either your hardware doesnt support it or the issue is in the kernel run hdparm through strace and you can see the ioctl's being sent to the kernel ... that means hdparm has done its job

So if it would use the ioctl it uses to get the "Current value" in the output of -I above in reporting the value with -M it should work.
Please attach output of "strace hdparm -M ..." and then attach output of "strace hdparm -I"

bump
Sorry for the delay in getting to this, other issues are taking priority. Please file this upstream at http://bugzilla.kernel.org -- hopefully it will get more attention there. Attach the strace output as well. Please post the new bug URL here when done.
