I am still unable to get zaptel to work with my "Wildcard TDM400P
REV I" on 8.0-RC1 with the MG2 echocan.  I experience the same issue
with my TDM800E (esentially 2 TDM400 cards on a single lane
PCI-express) probably because I ported the linux driver using the
the wctdm driver as the template.

It looks like the device nodes aren't correctly made.
