Pismo 3D acceleration!!!! YAY! Alert: long post!

[Felix Jodoin]

The hardware guide said it couldn't be done, but I found a way. 
Want full 3d acceleration on your powerbook g3 pismo?

First of all, get the system set up with kernel 2.6.9: 
Update the system
-then-
Edit your yaboot configuration files to make sure it's using that.
Remove the "append=rhgb quiet" line, and run ybin. 

Once you've done that, use the attached XF86Config configuration file:

Section "ServerLayout"
        Identifier     "XFree86 Configured"
        Screen      0  "Screen0" 0 0
        InputDevice    "Mouse0" "CorePointer"
        InputDevice    "Keyboard0" "CoreKeyboard"
EndSection
 
Section "Files"
 
# RgbPath is the location of the RGB database.  Note, this is the name
of the
# file minus the extension (like ".txt" or ".db").  There is normally
# no need to change the default.
# Multiple FontPath entries are allowed (they are concatenated together)
# By default, Red Hat 6.0 and later now use a font server independent of
# the X server to render fonts.
        RgbPath      "/usr/X11R6/lib/X11/rgb"
        FontPath     "/usr/X11R6/lib/X11/fonts/misc:unscaled"

Don't include that end of file line ;)
That will give you 3D acceleration!
