I wasn't contradicting you.  A new feature that can be supported by
different hardware and is quite useful deserves a unique flag, and I
definitely agree with that.  I don't to see my desktop flattened top to
bottom if I can prevent it.

But aside from the above, I also need a field which is interpreted
differently from driver to driver, and is so nebulous that it doesn't
deserve its own flag.  Just something that can be used to poke the
hardware from user space without writing a utility each time. 
Currently, I'm doing this by setting bits in var->nonstd.
