Garrett: Rebooting

There's a firmware patch for the PC I'm writing this on (a 64-bit mainstream PC that's less than 5 years old) which supposedly fixes the following bug which I have verified exists:

* Reset does not work. After the rest button [a hardware button] is pressed a corrupt screen is displayed and the computer does not work until physically powered off.

I have never applied this fix, if that's a bug that survived into shipping hardware, why would I conceivably want newer versions that presumably went through the same worthless QA process and may have worse bugs?
