I have the G4/733 DVD-R Mac ( The one before the quicksilver I think) with the NVidia GeForce 2MX

I use two configurations with YDL 2.2 and XFree 4.0.2
1) video=riva:1280x1024-8 at 85 console driver and fbdev XFree driver
I can choose the resolution of the console at boot time and XFree at multiple resolutions
2) video=ofonly for the console and nv driver in XFree
I am fixed at the last Mac resolution for the console, but XFree can run at multiple resolutions.

I enclose the relevant entries from my XF86Config-4
Note: not all resolutions listed actually work (maybe dot clock, hsync or vsync limits)
