-Get the memrar driver cleaned up and upstream (dependency blocking SST)
-Replace long/short press with two virtual buttons
-Review the printks and kill off any left over ST_ERR: messages
-Review the misc device ioctls for 32/64bit safety and sanity
-Review the misc device ioctls for size safety depending on config and decide
- if space/unused areas should be left
-What the sound folks turn up on full review
-Using the ALSA frameworks properly
