How can software get that broken

So I update my main workstation running Linux to the latest, greatest release. To my surprise the already not so fast xf86-video-nv driver stopped working entirely. I get no video signal either on the laptop’s internal LVDS panel, nor the external, DVI port. As quick, even slower, fallback at least xf86-video-vesa still worked. Just on the internal display, of course. At least something. However, my biggest surprise was still ahead: The keyboard layout kept constantly changing! Between English(US) and German(DE) !!!! How am I supposed to type, work, that way, heh? Even entering my login password became a challenge only cut’n paste could solve, …

How the heck can software regress that majorly. Ok, well. Random hacking might explain it. Too many cooks spoil the broth. But really. ‘nough is ‘nough. The machinery worked better 10 years ago in the days of XFree86 on my then 120MHz Intel Pentium, 233MHz IDT Winchip 2(a or so). Certainly some S3 Virge3D, later Matrox graphic cards.

Update: Good old modeline stuff segfaulting, yuck:

Program received signal SIGSEGV, Segmentation fault.

Update 2: Not soo much good-old-modeline as guessed at first - more so newly added gamma fluff, … bug - so basically the whole X server setup is crashing in many combinations and cards since last November??? What a fun.
