An AdLib card is just an OPL2, which was already supported by sound/drivers/opl3, so only very minimal bus-glue is needed. The patch applies cleanly to both 2.6.16 and 2.6.16-mm1. The driver has been tested with an actual ancient 8-bit ISA AdLib card and works fine. It also works fine for an OPL3 {,emulation} as still found on many ISA soundcards but given that AdLib cards don't have their own mixer, upping the volume from 0 might be a problem without the card driver already loaded and driving the OPL3.
