asterisk users - Feb 2005 - Using zaphfc and wcte11xp at the same time problem

I am having problems loading the zaphfc from bristuff and wcte11xp
drivers at the same time.
If I load zaphfc then all works fine.
If I then load wcte11xp, the card using the zaphfc doesn't pick up calls
anymore.
I am using bristuff 0.2.0-RC5.

Anyone else seen this problem, know of a fix, or can tell me what I am
doing wrong?

Thanks

My zaptel.conf:

# hfc-s pci a span definition
# most of the values should be bogus because we are not really zaptel
loadzone=nl
defaultzone=nl

span=1,1,3,ccs,ami
bchan=1-2
dchan=3

span=2,0,0,ccs,hdb3,crc4
