Thanks for your reply, Andre.

Okay, this has happened repeatably on two Acer Altos boxes.  Sorry to be so
silly, but I can't think what else I can configure.

The jumper on the disk is set to master, it is plugged into the primary using
an ATA100 cable, the power is on :-)

On the other dual CPU box (using older kernels), I could boot into a single
CPU kernel on the machine, and the disks would work.  Boot into a SMP kernel,
no recognition of the bus in /proc/ide, and fdisk reports the other disks,
but not those plugged into the cmd card.  The cmd64x driver is compiled
directly into the kernel, not loaded as a module.

Any other suggestions?  Where can I find more evidence?  Willing to try
anything!
