Worked for me after rebuilding cache...

For OS X 10.10.2, apply the following patch:

<dict>
    <key>Comment</key>
    <string>Bootloader Graphics - Second Stage Patch</string>
    <key>Find</key>
    <data>QYjE6xE=</data>
    <key>Name</key>
    <string>IOGraphicsFamily</string>
    <key>Replace</key>
    <data>QYjE6zE=</data>
</dict>

It doesn't work on T440p(HD4600, patch with FakePCIID.kext & FakePCIID_HD4600_HD4400.kext )

Post the config.plist you're using.

Worked for me, i'm not sure, but i think it might have solved my occasional glitchy graphics when using launchpad.

Increase your frame buffer cursor bytes.
