Yes i did!
Works pretty good on my HP530, some minor glitches like random slowdown (rarely)
when using Expose, and a "ghosting" effect using the Flurry screensaver (always)
Here's a quick howto*:
0 backup your gma950 kexts!
1 you need the right hexeditor, most of them out there seem to miss a "string search option"
So use Hexfiend :
http://ridiculousfish.com/hexfiend/2 Copy the files:
/System/Library/Extensions/AppleIntelGMA950.kext
/System/Library/Extensions/AppleIntelIntegratedFramebuffer.kext
to a folder on your desktop
3 Launch hex fiend and search/replace "86 80 A2 27" in both files (see how the bytes are swapped?)
with "86 80 AE 27". without the quotes ofcourse. if you do it right, the total number of replaced strings
will be +/- 51 (25+26).
4 copy both files to /System/Library/Extensions
5 repair permissions
Tested with 10.4.8 jas edition and xxx 10.4.11 not with 10.5(.1/.2)
