Yes, you probably have a sym53c8xx based driver, and it needs the
scsi_transport module which Jens mentioned was missing. Jens added it to the
modules, but i am waiting for Jens to rebuild a powerpc kernel based on the
2.6.8-5 kernel-source to make a new upload. This should fix this problem.
In any case, could you go to console 2, and give us the content of /proc/pci
and /proc/bus/pci/devices, so we can confirm that this is it ?

Ok.
