trouble with comedi_config and cio-das1602/16

I recently upgraded(?) from a vintage metrabyte das16 board to an isa 
cio-das1602/16 board.  The cio board seems to function properly in instacal 
(dos), but i am having trouble configuring it under comedi.

comedi_config /dev/comedi0 cio-das1602/16 0x300

works, and gives:

comedi0: das16: 0x0300-0x030f 0x0700-0x0708
  id bits are 0xc0
  1MHz pacer clock
  ( no irq ) ( no dma )

in the kernel log.

Any attempts to pass additional options, like the dma channel causes 
comedi_config to print it's help screen and exit while doing nothing.  This 
is a bother since the cmd interface requires at least a proper dma 
configuration.  My comedi setup was working with the older das16 board so the 
trouble seems to be related to the change.

comedi version 0.7.70
comedi_config version 0.7.16
comedilib version 0.7.22

TIA
