Why are you so desperate for TDM400P cards?  Don't put more than three 
Digium cards in one box.  IRQ shareing is one of the problems.  There is 
also the problem that each card generates 1,000 interrupts per second. 
If you want more than 8 or 12 ports then get a T-1 card and a Channel 
Bank.  The channel bank will convert the T-1 channels to/from Asterisk 
into analog ports for you.
