The answer there is not to maintain two different systems with different bugs in each of them but fix the one that is there for the longer term

Especially given that the non-KMS code is not just 'messy' but
misdesigned. Multiple drivers in kernel and userspace arguing over a single video card is pretty much obviously a bad idea. If video cards on PCs had never been capable of displaying text, I suspect this design would never have lasted as long as it has, at least on Linux: this meant that most people could just use a text-mode console and pretend that there was only one graphics driver, the 2D X one, when in fact the other driver was in the video card...

Agreed. Clearly maintaining both is not viable. All I'm proposing is not removing the non-KMS code until the KMS code is stable and usable. Importantly, that has to include older hardware (not obsolete, just not cutting edge). It seems there's been a reasonable amount of work on getting KMS working with newer video cards. But it needs to work on cards that are 3 or 4 years old, too, and based on my experience, it currently doesn't.

Have you reported your bug? We can debate on what is the right threshold but it is also the case as long as there are two different systems end users tend to switch between them and never report bugs

Yes. For better or for worse, I report every problem I find as a bug. The usual response seems to be to ignore it, wait for a year and then close the bug because it's for an unsupported release. But I have to keep trying...

It certainly should work with older hardware: my 2000-vintage system (now
reserved for compatibility checking) with its Radeon 9250 is quite happy with KMS.
However ATI have a crazy variety of cards, all wired up slightly
