Apple addresses MBP17 vertical lines with firmware update

Apple today posted MacBook Pro Graphics Firmware Update 1.0 (770kb) which addresses the appearance of vertical lines or distorted graphics on the notebook display. According to the about page there are two parts to this process:

1. Installing the firmware update application onto your hard drive.
2. Using the firmware update application to update your graphics subsystem firmware.

A long thread in the Apple Discussions forums implies that the vertical line issue may be a result of defective Nvidia GeForce 9600 graphics processor chips. The issue doesn't manifest itself when running on the less-powerful Nvidia 9400 GPU.

If you've experienced the issue, post your results after installing the firmware update in the TalkBack below.
