10.6 display drivers in 10.5

[sporadicMotion]

I'm trying to force my 10.5.6 install to accept my 10.6 drivers on my MacBook to see if there's any benefit. This is what I tried:

Copied AppleIntelGMAX3100.kext to /System/Library/Extensions/

went to terminal and under root user:

chmod -R 755 /System/Library/Extensions/AppleIntelGMAX3100.kext
chown -R root:wheel /System/Library/Extensions/AppleIntelGMAX3100.kext

I then deleted the extension cache and rebooted... BUT system profiler shows that OS X won't load the drivers. Any thoughts.

Please don't ask me to send you 10.6

I highly doubt the drivers will have changed, stick with 10.5.6 for now.

And send me 10.6 JK, it's been all over torrent sites for ages

You'll probably end up causing a kernel panic - I've played around with drivers before and ended up mucking up OS X to the point where it wouldn't boot past the Apple logo and needed to mount my hard drive to another Mac and sort it out.

If you are trying to compare the benefits and already have 10.6, then why not test something on 10.5 and something on 10.6.

Finally to add, I don't think the Intel integrated drivers are going to get much more optimisations/improvements anyway.

The version number is new and this is more of a curiosity issue anyways. I've already done comparisons under 10a222 and 10.5.6 and it's hard to simply test the video driver improvements with the other improvements under SL... for example, Xbench showed a CPU jump from 124 to 141 which is primarily from the Floating Point operations. I'm not worried about crashing the system as I'm using a separate installation to do this and I'm not messing with my primary OS X installation.

It's fairly unlikely that the internal APIs those drivers are using remained the same between 10.5 and 10.6, so I'm not surprised they don't work.

so,can anyone tell me if 10.6 works or will work on PPC?

You never really know until the final version. But probably not.
