OK, it's monday and I'm back at work ;)
The controller is a "LSI Logic / Symbios Logic 53c1030 PCI-X Fusion-MPT 
Dual Ultra320 SCSI".
I booted into a loader prompt and entered "load amr". Result was a
/boot/kernel/amr.ko text=xxxxxx data=xxxxxx syms=xxxxxxx
so I guess the driver has been loaded successfully.

If I then enter "autoboot" to start booting, system still cannot found 
root. If I enter "?" to show valid boot devices, I only get acd0 
(CD-ROM) and fd0, so I think the amr.ko could not detect the controller...

any ideas? Is the amr.ko to old for this controller? is there a new one 
around?

thanks!
