I've got 1.6.0-rc4 up again.

cat /proc/dahdi/*
Span 1: WCTDM/4 "Wildcard TDM400P REV I Board 5" (MASTER)

	   1 WCTDM/4/0 FXOKS
	   2 WCTDM/4/1 FXOKS
	   3 WCTDM/4/2
	   4 WCTDM/4/3 FXSKS

and dahdi_cfg seems to have worked:

dahdi_cfg -vv
DAHDI Tools Version - 2.0.0-rc2

DAHDI Version: 2.0.0-rc3
Echo Canceller(s):
Configuration
======================


Channel map:

Channel 01: FXO Kewlstart (Default) (Slaves: 01)
Channel 02: FXO Kewlstart (Default) (Slaves: 02)
Channel 04: FXS Kewlstart (Default) (Slaves: 04)

3 channels to configure.

Changing signalling on channel 1 from Unused to FXO Kewlstart
Changing signalling on channel 2 from Unused to FXO Kewlstart
Changing signalling on channel 4 from Unused to FXS Kewlstart

but still no luck. No dial tone for the internal phones, no answer on pstn.

BTW, this file is sometimes referred to as dahdi.conf - to keep us on 
our toes.  and what is the comment sign ; or # ?
