I tried this XF86Config on my PB G3 Series, and although it starts up, it is still running in Open Firmware (non-accelerated mode).

Did you try running fbset -i while the Xserver is up?

I could be wrong, but it seems to me I remember reading somewhere that you can't run XF68_FBDev in accelerated mode when the console is running Ofb.

Xpmac is much faster than Ofb; try moving an open window around.

Finally, I got it !
XFBDev on PBG3 series, now the TFT screams ! I never though it would be that good.

So it turns out that it was the lack of valid video mode that prevented XFBDev to work properly (actually, to display properly). Now I have the following /etc/XF86Config :

Does the XFBDev out specifies it's using the ATY Rage PRO device, with acceleration enabled ?

If not, try video=atyfb:vmode:14,cmode:8,mclk:83 as a kernel argument, with unchecked "no video driver" box.

If you not see atyfb;ATY RageLT PRO in the boot sequence (and later in /var/log/dmesg) then there is a problem.
If you do see it, then XFBDev should report it's using the ATY chip, in acccelerated mode and things should go... lightning.

I don't have fbset unfortunately, I think I have to grab it from G.U. site, yeah ?

Sure.

I wasn't able to make some use of Xpmac

Doesn't work; I get the "psychedelic death screen". Strangely, if I set the mclk to 43, the display is still messed up but I can hear the machine continue to boot.

I don't think I've heard of anyone using atyfb successfully on a 300mhz PB G3 Series.
