Radeon HD 5450 on PowerMac G5

Hi,
Having given all hopes of making work my Radeon 1950 Mac Edition on my
Quad G5 (because it lacks Atombios), I finally tried the Radeon HD
5450, because it is quite cheap these days, quite powerfull and silent
(no fan). The dmesg, looks mostly alright on Debian Testing (kernel
3.2.0), but it seems that the card is mostly unable to correctly
detect any monitor plug in any of the 3 port (DVI, HDMI or VGA).
Here is a collection of information:

Xorg was unable to detect any other screen than the screen plugged on
my NVidia card.
I discussed the issue on the debian-ppc mailing list a few weeks ago,
and the conclusion is that there is a probable bug in the radeon
driver (maybe an endianess issue in the Atombios interpreter). Anyway
I was told to seek further help on this mailing list.
I am ready to do a bit of testing if required (I can compile a brand
new kernel or modules if required, I only need some help with git if I
have to use it since I rarely use it myself). I join the full dmesg
and Xorg.0.log (here the server is launched without xorg.conf)
Thank you for any suggestion. Please CC me when replying.
