--- Comment #21 from Brent <bzipitidoo at hotmail.com> ---
Tried the noaccel and nofbaccel kernel options under Puppy Linux 6.0 with the
3.17.7 kernel.  Didn't make any difference to the display, it is still bad, in
the same way as without those options.  Xorg.0.log confirms that acceleration
is indeed off.  It is mostly the same as the log I uploaded here, except after
the line "(--) Depth 24 pixmap format is 32 bpp", I see:

(EE) NOUVEAU(0): Error creating GPU channel: -19
(EE) NOUVEAU(0): Error initialising acceleration.  Falling back to NoAccel
(==) NOUVEAU(0): Backing store enabled
...

I also tried kernel 3.10.71 on the Arch system.  It was no different than
3.4.106-- [drm] failed to open device.  Yes, I know there could be an API
mismatch, and maybe the 3.4 and 3.10 kernels would work with a more recent
XWindows.
