I found this message in the als archives.

Summary:
I had quite a few conversations via email with David Sowa at Ensoniq,
ran a boatload of tests, found that the card worked fine in a
different system, swapped cards, and finally learned the answer. Turns
out that there's a hardware bug in one batch of one vendor's codecs,
which causes them to lock up if the PCI reset-line timing is just so.
The ALI chipset in my ASUS motherboard tickled the bug, while the Intel
chipset in my test system at work did not.


I have been watching the list to see if anybody has found a solution
to the problem.

I've had at least 4 reports of the new PCI128 not working with an ASUS board.
