PCI DDA08/16 8255 Configuration problem

Hi...we have been trying to get a Measurement Computing DDA 08/16 board to 
talk to a simple process that writes a waveform to all analog output 
channels...in addition to this we are also trying to write a square wave 
over two digital lines to synchronize our code...the 8255's on the PCI DDA 
08/16 should be accessible...however while loading the driver we notice 
two messages pop up saying 

"8255 support not configured -- disabling subdevice"

the board seems to respond ok on low frequency signal 
generation...is there anything we need to change on the 
install/config...our modules are loaded in the following 
order in the rc.local

8255
cb_pcidda
cb_pcidas
kcomedilib
comedi 

after which we run the comedi_config command for the two boards in our 
rc.local as...

"comedi_config /dev/comedi0 cb_pcidda"
"comedi_config /dev/comedi1 cb_pcidas"
