Modprobe crash with AEC-6280 Acard PCI-card

[Kaspar Fischer <fischerk@inf.ethz.ch>]

Hi everybody,

I am running Debian Sarge on an old PowerMac G4,

  > uname -a
  Linux backup 2.6.8-powerpc #1 Thu Nov 24 00:17:15 UTC 2005 ppc GNU/ 
Linux
  > # http://www.everymac.com/systems/apple/powermac_g4/stats/ 
powermac_g4_733_qs.html

Since I want to use the machine as a file server, I intend
to add an AEC-6280 Acard PCI-card to connect some more IDE
harddrives.

After installing the card, the machine boots and crashes; I
only have a small screen but what I see is more or less this
(warning: I manually copied this from the screen).

What could be the cause of this?

Thanks for any help,
Kaspar

P.S. I had a problem with this card before, on another machine,
