Yes.

I tried with 2.4.25 2.6.4 and  2.6.8

Yes, the module segfaults.

You are right I will report it.

The card is not initialized at all. (Got no address in PCI space)
A friend checked it with a PCI hardware debugger:
During PCI initialization the AMI-card answers with ABORT.
Because of this the cards gets no address space from the firmware.
So its not recognized as a PCI card at all.

You are right. The card belongs to a friend I have to ask him for the 
error messages again.

Good point.
If the cards Bios is x86 assembler running it will be a bit difficult.

Are there any Raid card which have a forth bios?

Regarding the tools:
I hoped to be able to setups/admin a raid with program like the linux 
raidutils.
