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