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

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?
