Summary:                    TE220 and TDM400P, random module load order on
reboot, channels swap!
Description: 
On reboot udev configures one or the other card first. Which results in the
spans moving arround.

If TE220 is found first, 'span 1 and 2' are assigned to this card.

If TDM400P is found first, 'span 1' is assigned to this card, and spans 2
and 3 are assigned to TE220P. This results in asterisk not loading
'chan_zap.so' as channels are misconfigured, if (in our case) the
configuration expects TE220 first.

This can be seen by running zttool after reboot:
(Working)
   |     OK              T2XXP (PCI) Card 0 Span 1                      
|
   |     RED             T2XXP (PCI) Card 0 Span 2                      
|
   |     OK              Wildcard TDM400P REV I Board 1                 
|

(Broken)
   |     OK              Wildcard TDM400P REV I Board 1                 
|
   |     OK              T2XXP (PCI) Card 0 Span 1                      
|
   |     OK              T2XXP (PCI) Card 0 Span 2                      
|

current workaround in /etc/init.d/fixzaptel is to unload and reload
modules in a predicatable order.
        /sbin/rmmod -a wctdm wct4xxp zttranscode zaptel
        /sbin/modprobe -q -a zaptel wct4xxp wctdm
        /sbin/ztcfg
