Issues during Installation of Lion on my X60t

Stuck on “_” on boot

Chameleon is not installed properly

Stuck on black screen or reboot on Darwin x86 loading (mach_kernel)

CoreDuo issue … Install on a Core2Duo, modify and boot on CoreDuo
use mach_kernel from DP1

Firewire KP on boot

Might be related to bad DSDT edit … I deleted every firewire kexts from /SL/E/

Very low brightness on boot

Not DSDT.aml related … will try another smbios.plist
Not smbios related … will try EFI string
Not EFI string related … will try custom kext
Worked with the files from this page … (no QE/CI)
I think only "AppleIntelIntegratedFramebuffer.kext" is responsible …
