Yes (I think) - I should have posted a patch for this. in drivers/char/mem.c there are two areas in which calls (and its declaration) to init_dmasound() are conditional on CONFIG_DMASOUND - but CONFIG_DMASOUND has been removed. You need to change those lines to something like... #if defined(CONFIG_DMASOUND_AWACS) || defined(CONFIG_DMASOUND_ATARI.... or whatever (the various CONFIG_DMASOUND_XXXXX are visible in the Makefiles) Sorry about this - I was very new to the list and carried out some of the discussion without doing cc's ;-) I think that is it - basically you have everything complied in - but it isn't being called at init time.
