Sounds like you would be fine if the power completely drops out. but 
there are 2 things I can
think of.

In zconfig.h (in the zaptel directory) there is a line at the bottom (at 
least in my cvs version)

/*                                                                                                                                  

 * Uncomment if you happen have an early TDM400P Rev H 
which                                                                        

 * sometimes forgets its PCI ID to have wcfxs match essentially 
all                                                                
 * subvendor 
ID's                                                                                                                   

 */                                                                                                                                 

#define TDM_REVH_MATCHALL    

The other is a bit more involved and can be found here:

This might be a bit different with the newer software, but the basic 
idea is the same
