     62  * Software state, per SoundBlaster card.
     63  * The soundblaster has multiple functionality, which we must demultiplex.
     64  * One approach is to have one major device number for the soundblaster card,
     65  * and use different minor numbers to indicate which hardware function
     66  * we want.  This would make for one large driver.  Instead our approach
     67  * is to partition the design into a set of drivers that share an underlying
     68  * piece of hardware.  Most things are hard to share, for example, the audio
     69  * and midi ports.  For audio, we might want to mix two processes' signals,
     70  * and for midi we might want to merge streams (this is hard due to
     71  * running status).  Moreover, we should be able to re-use the high-level
     72  * modules with other kinds of hardware.  In this module, we only handle the
     73  * most basic communications with the sb card.
