I also updated my vanilla iDeneb v1.4 to 10.5.8 and if i use the ApplePS2Controller.kext I get panics.
I can run using my usb KB/Mouse.
So I'm still looking for a fix.
all the files I have tried thus far panic!
Nevermind, luckily before i updated from 10.5.6 to 10.5.8 i made a backup of my extensions using OSX86 Tools and restored them when the update was complete.
My Touchpad, Keyboard, and Sound now work =D
Then I decided to have a go with the chameleon rc2 bootloader and it works great! It looks awsome man i recomend anyone to get it.
Also i had to reinstall the seatbelt kext to prevent kernel panics on mounting dmg's.
What i need to get fixed is the sleep, because it just doesn't work. Before i installed chameleon rc2 i had the command line darwin bootloader and when i went to boot up it said something about sleep failed and hibernate failed, I'm not sure what it said, so that might be a reason why it aint working, but hey the chameleon rc2 might have fixed it??
I will reply with the answer, i will go on check now.
