Just the trickiness of dealing with a BE cpu and a LE-but-kinda-BE-sometimes GPU. Unfortunately I don't have a clear model in my head of precisely what all the "BE" flag flips on these GPUs, which makes things much trickier. > > ...

It's a PowerMac7,2 IIRC. It has an AGP slot (with the FX 5200) and some number of PCI slots. I glanced at nv4x boards, but they're above my tolerance of things I buy for the purpose of developing free drivers in my own time.

Oh interesting. That means the confusion is in the DDX. (Or disagreement between mesa and the DDX.) Please confirm that you're running a semi-recent version of xf86-video-nouveau (e.g. 1.0.12), and actually verify that it says NOUVEAU(0) in your xorg log.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
