The kernel dated Dec 6 works fine. The kernel compiled from yesterday's sources detects and attaches the card, but there is no sound. mpg123 (and other programs) hang in "pcmwr" (tsleep in pcm/channel.c). Both the new and old kernels report the card as: pcm0: <CS4231> at port 0x530-0x53f,0x310-0x311 irq 5 drq 1 flags 0xa210 on isa0 The card is non-PnP, so PnP-related fixes are not responsible. I suspect it has something to do with the recent DMA underrun/2nd buffer changes to pcm/channel.c. I'll try to investigate further.
