sdparm is a nice tool. You can compile it without problems and I tried it but 
it lacks (or I have not found a way)
to create/ display/ modify/ delete host protected areas. This seems a hdparm 
feature only.

I can create a HPA  now on Linux and Windows with tools from the SSD vendors 
but Solaris & Derivates is the Storage OS par excellence.
We should have such a tool as well.
