I did the same thing but used __get_dma_pages instead of __get_free_pages.
It works for me and I believe it should work for everyone. The original call
appeared to be asking for DMAable memory which the __get_dma_pages function
should return. I've got 64meg of RAM and a 16bit sound card, I'm not sure
whether the version you posted would work for me, but I expect it would work
well for everyone who's got 16megs of RAM.

BTW Does anyone know of a good PCI sound card that has Linux support? I'd
like to go all-PCI and avoid the problems of 24bit DMA etc altogether.

In return for "mailbag contention" errors from buggy Exchange
