I didn't know about the later two : thanks for sharing this.
May I add that Linux automatically  "allocates" hfc4s8s_l1 driver to
Junghanns OctoBRI cards which are supported by Dahdi, so I add to
blacklist them in the past.

This shows me I should learn :
- how Linux 2.6.32 (and above) detects PCI boards and "allocates" them
to mISDN (the one included, I think, in the kernel itself)
- where to find up-to-date data listing telephony cards either
supported by Dahdi or mISDN

I was a bit luckier thanks to default dahdi.blacklist.conf file.
