[silverblade] 39797: Started new implementation of Sound Blaster driver (kernel mode), which at present just looks at the settings in the registry (actual sound blaster code to go in a dedicated library elsewhere for later reuse in portcls.) Also updated wdmaud.drv - it can only identify how many devices have been reported by janderwald's code at present.

Log:
Started new implementation of Sound Blaster driver (kernel mode), which
at present just looks at the settings in the registry (actual sound
blaster code to go in a dedicated library elsewhere for later reuse in
portcls.) Also updated wdmaud.drv - it can only identify how many devices
have been reported by janderwald's code at present.
