There is an opb core developed for the Xilinx University Program board, which has a similar hardware interface to the ML403 (i.e. no PCI bridge) The XUPV2P web page with the opb_ac97 core is here: http://www.xilinx.com/univ/xupv2p.html
I have a /dev/dsp driver (which I'll send to Bert directly) which limps along in 2.6. This core has a relatively small buffer and no master access to memory, which results in relatively poor performance, but it is a starting point.
