Do you mean one of the bigger regulators with the heat sinks? Then the whole
machine should not work any longer, I think. There is another 7805 (surface
mount) which I think is used for analog supply only. Then there is a 7812
with small heat sink. I thought the 12V was needed for the smartcard, but it
could be for the serial port as well. The serial port uses a maxim part, so
it should work on 5 volts -- strange.

How come the io port range on the BSD setup starts 4 bytes lower than 0x830?
Maybe one of the other small chips on the board implements the PnP stuff for
the CS4231A?

Does it hang when you do the modprobe command, or when you try to play back?

The only other device in the box that uses ISA-style DMA is the floppy disk
controller. I don't have access to hardware right now, or I would try to configure
a kernel with floppy driver. The National Semiconductor SuperIO chip contains a
floppy interface, and that may be bumbling around on dma 0 unless configured.
