One reason X won't listen for c-a-bs is that it's configured not to. And 
that's now the default setting.

I do most of my work at VTs, I configure an even dozen of them on most 
of my systems, and then use screen for good measure. I also boot with 
VGA=794, and where that doesn't work I use modprobe and fbset to get a 
1280x1024 framebuffer. If I can't get that, I really do not want to use 
that computer.
