Thanks for the fast reply!
Ok. This is what I do:
1. Open Marvin > Select (create patcher package ) > select my Leopard volume to scan (scan takes like 5-10 minutes)
2. Copy patches folder to the root of my leopard volume
3 reboot in single user mode (-s ) then cd /patches then ./ patcher ./cpuid.txt
(runs the i get this:0 of 2 visited files were successfully patched
0 of 11 found patches were successfully applied
This is the cpuid.kext:
2
0f a2
cd fb

/Applications/Firefox.app/Contents/MacOS/libfreebl3.dylib
00001e44
0003fe2c cpuid
