| > no support for DHQ11 8-port serial card
| Are the DHQ11 the same as DHU11? Otherwise, there are no support for 
| that serial card yet.

I believe the DHQ is just a dual version of the quad DHV board.  I vaguely
recall the DHQ has a few extra bells & whistles but I am fairly sure it
is just yet-another-DHV.  Does the hardware configured address (dip
switches) match the kernel gen'ed DHV address(es)?  -- Ken
