I just bought a mac 9800xt card to replace my 9600pro on my G5 running gentoo ppc64 linux(2006.0, 64-bit userland). The system worked fine until I started xorg-7.0: the screen blacked and the keyboard and mouse were not responding any more, so I had to shutdown the machine. The same X config worked well with 9600pro card(64M). 
I tried also ppc32 chroot on my system with xorg-6.8.2, it worked as expected. The last part of Xorg.0.log file is as follows, which was left by the broken xorg-7.0:

Here is some info about my card and X:

I noticed the 9800XT card was identified as 9800PRO, R350, but it's R360 under MAC OSX. 
Is that specific for ppc64 linux 64-bit userland? I haven't tried xorg-6.8 or 6.9 on my ppc64 with 64-bit, but for 32-bit userland 6.8.2-r6 has no problems.
Thank you in advance, any help is highly appreciated.
