This is my simple solution for Lenovo & GMA X4500 users until we have final driver without mouse bugs & supporting CI/QE, so you can set screen resolution to 1280x800@60Hz or whatever you want & working mouse without mouse pointer disappear.
Please Note, there is NO Kext loaded & no CI/QE, this steps success in my laptop (lenovo 3000 N500 4233-65G).
1--- Make a clean installing for iATKOS_v7 10.5.7 & select one of boot loader (Chameleon v1 or BootThink v1).
*** Don't select Chameleon v2, in my case, I had failed to update it later, or test it at your risk.
2--- Update to Chameleon 2.0RC2 Build r640 & Repair Disk Permissions and reboot twice to ensure that your installation success.
3--- looking for screen resolution available to your machine from (Video Info) in Chameleon boot screen.
Make Test, just boot in (Verbose) mode and type your screen resolution or type this.
CODE
-v "Graphics Mode"="1280x800x32@60Hz"
Now, you have 1280x800 fixed resolution without mouse disappear
4--- Run (OSX86Tools), select (Add EFI String/Boot Flag) & Add this code to (Flag) Field
CODE
"Graphics Mode"="1280x800x32@60Hz"
Press Apply, Reboot & Success.
Best Regards.
