o Add signed/unsigned functionality to the matrox meteor device driver. o Apply a few fixes to the sound driver. o Add a ``SPIGOT_UNSECURE'' compile time definition so, if one defines SPIGOT_UNSECURE in their conf file, then they can use the spigot w/o root. There is a warning that this allows users access to the IO page which is probably not secure. Submitted by: james
