... at least for PPC targets.
There was a set of patches applied for the 2.4.21-rc2 kernel
(some seem _very_ strange, maybe endianness issues...)
that makes sbp2 fail to recognize my external firewire drives.
The only way I have for now to make things work is to come back
to the 2.4.21-rc1 version, which work correctly for my Mac
and my PC (VIA Chipset & Firewire chip).
On the Mac (Ibook), I can see my disks in /proc/bus/ieee1394/devices:

Here's the output of /proc/scsi/sbp2/1 (with the working driver):

I may do more tests to localize the bug, if I only knew which ones I
should do...
