That's not going to be enough: this ID has been in the aacriad driver
since 2011.  That means anyone who finally gets hold of one of these
new cards but uses a distro that doesn't have the new smartpqi driver
will be attached via the aacraid one.

Given that the life times of enterprise distributions is two years and
you're releasing this smartpqi soon, the overlap is unavoidable.
