I sent the test results of the target disk mode last night.
Now this evening I tried to connect the alubook to the titanium via the FW
400 ports with both machines fully booted.
First the alubook with OSX connected to the titanium with Linux on it,
and then both computers connected to each other with Linux running on
both of them.
The alubook is a dual-boot machine (OSX/Linux), while the titanium
only has Linux on it.

PART I
Connecting the alubook (with OSX running) to the tibook (with Linux running)
---------------------------------------------------------------------------
Status on the titanium, with a kernel 2.6.14-1, IEEE1394_VERBOSEDEBUG
is enabled there.
After modprobing raw1394 the connected AluBook (OSX running) is seen
via gscanbus, but /dev/sda is not created. sbp2 was not started at
that time. modprobing sbp2 does not help to change this.

This is what OSX (on the alubook) says:
---------------------
.. about the titanium with Linux running: No pasting possible of the
values I saw: I wrote it down what I saw on the OSX screen:
Network status in OS X System Preferences reports something like this:
"Built in Firewire"
"Cable for built-in Firewire is connected, but your computer does not
have an IP address and cannot connect to the Internet"
I didn't even try (never will) to reconfigure this - I don't trust OSX
enough to let it come closer than 500 meters to my Linux partitions.

As I already wrote: Tuesday or Wednesday I'll have the git kernel
compiled, if all goes well. With CONFIG_IEEE1394_VERBOSEDEBUG enabled.
Note: About 2 days ago I had, IIRC, ext2fsx
(http://sourceforge.net/project/showfiles.php?group_id=64713) shortly
installed on OSX - I quickly uninstalled it afterwards, and at the time
of the tests today on OSX nothing *should* have been installed of that
software anymore .. let's hope :)
I do not know too much on OS X, that's why I keep my hands off Linux
via OSX.
Until then
Best Regards
Wolfgang
