I tried, I got passed around from person to person until i'd heard the
script at least 4 times, so I gave up.  Might try again tomorrow.
I'm currently testing the same card in a different server, with a Tyan Intel
chipset board, as opposed to a HP / AMD chipset.   I'm somewhat more hopeful
about this.  I was told that newer servers have some proprietary PCI bus
chips, which are optimised to deal with RAID cards and suchlike, which can
be problematic when handing IRQ-heavy cards such as these.

I think this is actually interesting, because the current Asterisk server is
actually a Dell Optiplex desktop with a Pentium 150 in it.  Can't get much
more basic, but it works pretty well.  (the only reason we're attempting an
upgrade, is because the old asterisk 1.0 can't support features that the
management want to implement, and the physical box is taking up too much
space in the already cramped server room!)
