I decided to put the Norco 4618 card into the first PCI slot of my DS20.

It and the PMP support seem to like that location much better - I'm
successfully creating an array at the moment.

The system still responds, but accessing currently running filesystems
(another array and the local scsi boot disk) seems to "freeze" for 20-30
seconds.

Does kernel complain anything during the freeze?

I was able to move the graphics card to another slot (which for a period
in the past was also limited to the first PCI slot).

Maybe this will make sense to some folks out there - thanks!

To me, not much yet.  :-(
