I tried more experiments with the enclosure.

I forgot about the first rule for making hardware work with Linux - see
how it's done in Knoppix.
With Knoppix 2.4.27 kernel the enclosure works. However, I cannot
disconnect and reconnect it. With Knoppix 2.6.9 kernel it fails in
similar way as the vanilla 2.6.10 with updated ieee1394 (and patches to
make it boot on the system).
With Debian 2.4.27-2 kernel it fails. No block device for the sbp2 bridge
is created - cannot find any in either dmesg and proc/scsi.

Is there anything I could try to get the device working on normal 2.6
kernel?
Since all host adapters I tried so far vere VIA chips could the problem
be in the VIA ieee1394 chip?
I will try with whatever chip is in iMac:s if the kernel finds it.

Thanks
