In case it helps others, a couple gotchas that I had to dig and beat my
head against to get past...
  - building on FC2, use "make linux26" when building asterisk
  - also for FC2, a couple links in /usr/src named linux and linux-2.6
    and pointing to /lib/modules/2.6.8-1.521/build/ were needed to build
  - yes, the power connector on the TDM400P needs to be connected
    to the power supply
  - modify the zaptel init script to use modprobe instead on insmod
That last one killed me ;)
