CS5, 10.6.4, Nvidia 10.6.3 extensions, No Crash

Question

I though I should post this in it's own thread so you can find it instead of the one I buried in another thread yesterday
Yesterday I replaced the 10.6.4 Nvidia drivers with the drivers from 10.6.3.
NVDANV50Hal.kext
NVDANV40Hal.kext
NVDAResman.kext
GeForce.kext
GeForceVADriver.bundle
GeForceGLDriver.bundle
GeForce7xxxGLDriver.bundle
GeForceGA.plugin
Extensions/NVSMU.kext
So far after about 8 hours of processing images I haven't had any crashes in CS5 running 64bit mode. Before the extension replace about every 10 images or so I would get the screen flicker and total computer freeze. All preference settings in CS5 were exactly the same as before with the total freeze.
I did not clean caches or remove any fonts, only repaired permissions after doing the extension replace. I simple mounted the dmg backup image from 10.6.3 and replaced the files listed above. You should save these files from 10.6.4 first in case you want to restore them.
A word of caution, I would not try this on a computer without another available boot partition as you really need to be booted into another partition to replace the extensions. And if anything goes wrong you can easily restore the 10.6.4 extensions.

No problem yet and I just got done working with 2 multilayered psd files with type layers. Really stable and snappy since the 10.6.3 extensions were put into 10.6.4.
Are you  sure your problems are not font related. I don't why Apple keeps insisting on shipping and installing with every update, bad fonts. Maybe to make Adobe look bad?
I would strip every font out in the Library/Fonts and System/Library/Fonts folders that the OS will allow. That is what I always do after every OS update and I have had no trouble with CS4 either. Always clean font caches and reboot when you do this.
