So is that kind of "work in progress" or will never be fixed?

Well, this far I have two options: ssh or restart with console 
framebuffer-enabled kernel and other X settings, both of which are cumbersome 
solutions for dualseat.

Can I ask one more thing: what is causing those problems with console 
framebuffer on x86_64? If that thing is in kernel, I get messed-up screen 
time after time and console cursor blinking on primary video device
