No, I know the one you are thinking of. It used to be quite easy to get
the thing recognised as a SBPro with about three lines in pcisupport.c, but
that stopped working for me at about the time the old sound stuff (voxware)
started moaning about compatability shims.
Taknori Watanabe's patch (which I now have a variant that applies
cleanly to an up to date -STABLE if anyone wants it) is a rather more
sophisticated affair that makes sbc.c recognise the card and ess.c attempt to
drive it properly. I have been looking at it closely over the weekend and the
missing part seems to be the configuration of the on board DMA controller.
Tonight I intend to find some sample code that does it (the docs are
inscrutable) and patch it in.
