Laziness can save us!

The ATI has just released new version of their video drivers, so I pretended to install them. But then I newly discovered that the driver isn’t installed under linux-2.6.20. The problem was much more severe this time, so I just refused to dig down any more. I downgraded the kernel to the previous version, and everything went just smoothly. How much time would I save if I did this when I was installing the previous version of drivers?..
