I had exactly the same problem on the same machine.
Woody was not yet "stable", though.
Here's how I to solved the problem:
In short, I added temporarly another disk (on the scsi controller for
the cdrom), installed Woody just to be able te compile a 2.4.18 kernel
(with gcc-3.0, I had a problem compiling the DAC960 driver with
gcc-2.95).
Note: it seems the DAC960 drivers won't work either if configured as
module (you have to put it in the kernel).
I then copied my system to the DAC960-controlled disks.
It's no piece of cake, but since then (back november 2001), the
machine is running really fine (just a problem with aboot not choosing
automatically to boot, have to press "0" and <enter>, I don't care, I
don't have to reboot it often!).
PS: if you need the kernel or the config file, I can send it to you. I
even think I made a kernel package of it.
