Apple iBook G4 Graphics Update_1.0

This update is recommended for the 12-inch 1GHz, and 14-inch 1.2GHz iBook G4. It updates the graphics driver to fix a compatibility issue that may exist with applications that use OpenGL.

When this update package is downloaded and installed it will replace the old ATIDriver.bundle with a new one.

This update only works with the new iBooks, the 12" and the !4". However, as the graphics chip in the prior models is the same it should work there as well.
That information is available now on xlr8yourmac.com and a hacked version of the installer is at http://www.analogrecycling.com/ibook/ibookG4.dmg
I tried this on my 933 14" iBook and it installed OK. There is no perceptible speed increase, but benchmarks show a small improvement in Open GL test results, making this a "not so necessary but interesting" update. Have not seen any detrimental effects at all, everthing seems transparent and OK.
Makes me wonder why Apple put the block in the installer, limiting it to the new models only, in the first place. Anyone know?
