Summary:                    [patch] Support for generic HFC-4S cards
Description: 
A patch to add some basic support of other HFC-4S -based PCI cards (such as
the ones made by Junghanns). 

Status: gets rid of the echo canceller messages when not needed, but still
needs work.

Specifically:
* It adds too broad a range of cards (which also include bero.net cards) 
* The range may include some 2-ports cards, which will probably not work.

Not yet tested to work, though it it is at least configured.

I succeded in getting "something" to work with a single span HFC
dmesg now shows:

dahdi_echocan_mg2: Registered echo canceler 'MG2'

and 3 channels are created under /dev/dahdi
but way it is in NT Mode ? Under asterisk I defined it as cpe ptmp, in
fact:

So way it starts as NT mode ?
(in order to make it starts, I had to trick and add 0xFF :
if ((x != 0xc0) && ( x != 0x80) && ( x != 0xFF)) {
