How do i load kext files into Chameleon and update using combo update?

[mookz]

Hi All,
I Do a lot of PC and MAC support.
I Have been struggling like crazy getting the Chameleon to work properly with official updates, i dont even know if this is possible.

Anyways i install iPC 10.5.6 final with all needed patches:

Base
StageXNU kernel Universal Kernel
Intel ICHx Sata Drivers
LegacyAppleIntelPIIXATA
ALC888
Seatbelt
AppleSMBIOS-27 rev6 iMac
OSx86 tools utility

i then bootup and everything is peachy.

I then install Chameleon 2 RC2 .pkg
reboot
and everything works well, boot loader works etc.
then i copy my kexts to /Extra/Extensions/
then i run
sudo chown -R 0:0 /Extra/
sudo chmod -R 755 /Extra/

sudo kextcache -a i386 -m /Extra/Extensions.mkext /Extra/Extensions
sudo mv /Extra/Extensions /Extra/Extensions1

reboot all is good

I then download
MacOSXUpdCombo10.5.7.dmg
run it
reboot
Chameleon starts up
and a Grey screen with the apple ...nothing else, it just hangs there/freezes.

Could anyone please assist me with this or do i have the whole concept wrong??

Use a retail DVD.

Thank you for the reply,
How would i install the retail DVD without the kexts?
I guess i would have to do the Chameleon USB key?
I feel like such a n00b 

and all this to train new techies how to use MAC's lmao
