I own this card since a few months, so I already tried it with several
older kernel, as they came in Debian Testing.
The behavior is consistent: it doesn't detect any monitor that I would
plug (older kernel were less verbose on the cause of the failure in
dmesg).

Which version of kernel would you suggest?

BTW here is my lsmod:

As you can see, the i2c_powermac module doesn't seem to be used. Is
there any module to make the link with the drm module?

Thank you for the suggestions
