There has been some confusion as to whether or not it is in fact WHQL'ed though.
It appears to be. Can you confirm or deny please, if possible?
Bear in mind lenovo's procedure for proper switching should you attempt this.
To check proper file copy, run "dxdiag" and "Save All Information" to produce a report.
I am only concerned with two sections. One being listed under "Display Devices" concerning "WHQL Logo'd:", the other concerning the files for any Display Devices.
... further down the file "dxdiag.txt":

If it is not WHQL'ed as i have been told, it is possible that some files may end up copied from Driver.cab or SP3.cab. A restart may be necessary for proper confirmation.
Thank you for any feedback. I look forward to properly crediting you in any changelogs, etc should you assist with testing this and/or any of the upcoming Graphics Nightlies which you will soon find in the Testing Forum.
