Ah, good! :-)

IIRC this also needs to be done with some applications, like Skype, to
get video working, but dunno why, though.

Looks good. The camera is detected and configured as UVC device.

(tip: you can append LANG=POSIX for getting messages in English instead
of your usual language)
Mmm... it is there in Lenny.
sm01@stt008:~$ LANG=POSIX; ls -l /lib/modules/$(uname -r)/kernel/drivers/ieee1394/raw1394.ko
-rw-r--r-- 1 root root 46435 Jun 13 20:48 /lib/modules/2.6.26-2-amd64/kernel/drivers/ieee1394/raw1394.ko

Ah, that can be then the origin of your problem.
But I wonder why the module has been removed or what a user needs to do
in Squeeze to setup the camera via firewire port :-?

This is from lenny:
sm01@stt008:~$ grep -e FIREWIRE -e IEEE1394 /boot/config*
# CONFIG_FIREWIRE is not set
CONFIG_IEEE1394=m
CONFIG_IEEE1394_OHCI1394=m
CONFIG_IEEE1394_PCILYNX=m
CONFIG_IEEE1394_SBP2=m
# CONFIG_IEEE1394_SBP2_PHYS_DMA is not set
CONFIG_IEEE1394_ETH1394_ROM_ENTRY=y
CONFIG_IEEE1394_ETH1394=m
CONFIG_IEEE1394_RAWIO=m
CONFIG_IEEE1394_VIDEO1394=m
CONFIG_IEEE1394_DV1394=m
# CONFIG_IEEE1394_VERBOSEDEBUG is not set
Mmm, looks very different. Sorry, I can't be of any help here, but just
found this forum thread where people talked about this, maybe you find
something useful there:
