Sadly, for T43's with Intel 915GM/GMS 910 GML Express Chipset Graphics, the Drives offered at LENOVO's Website do not help, you end up in a loop wherby after each system restart the driver is automatically removed by WIN 7. The Videocontroller remains without installed driver.
Connected VGA connected Screens or beamers would not be recognized either.
I tried out every version I could get a hold of. Finally I was successfull with Intel's support website: http://downloadcenter.intel.com/confirm.aspx?httpDown=http://downloadmirror.intel.com/14837/eng/win2k_xp142550.zip⟨=eng&Dwnldid=14837&keyword=Mobile+Intel+915GME+Express+Chipset
That driver works perfectly, if you rightclick setup.exe, set compatibility to XP SP2 and Administrator rights, then run setup exe. I hope this helps someone else too.
