How will they be 'screwed'? It seems like most people are making similar
upgrades without issues.

Watch your tone. You're barking up the wrong tree.

I did point out this problem a long time ago, but according to Dave
Airlie it's not really possible to make the X driver reliably detect
that KMS will be enabled in this scenario. In order to alleviate the
problem, I made the X driver bail. Previously, it would start up in UMS
mode, resulting in the kernel and X drivers both accessing the hardware
behind each other's backs. I hope you can see the potential for fun

Feel free to prove Dave wrong, but I just don't think it's worth it for
a corner case caused by broken configuration.
