asterisk users - Nov 2009 - [DAHDI 2.2.0.2] "failed on channel 1: No such device or address"

Hello

No matter if I use the entry-level OpenVox A400 with a single FXO
module or the most-often-garbage card from ww.x100p.com, I get the
following error after just adding this card to Mini-ITX with a single
PCI slot (OS = CentOS 5.4):

If someone's already seen this error message, any idea what the cause
is, and what I could try to solve it?

Thank you for any tip.
