The best reference is the 2.4.x driver. The netbsd driver is not a
bad refernce either.
The EBUS DMA engine is documented at:
http://www.sun.com/oem/products/manuals/802-7837.pdf
And that's likely where the problem are, the DMA controller and
the CS4321 chip aren't sync'ing up correctly. That was the most
difficult part of the driver to get right.

None at all, I wrote it all by myself using the ALSA ISA cs432x driver as
a guide.
