Funny, I can't reproduce the bug neither. I've removed some parts from 
my xorg.conf, maybe the problem came from here.

Yes, I've recorded a video [1]. Please note again that I can reproduce 
this bug only when I don't have any
firmware loaded / KMS enabled. I just boot with stock vt and vt_vga enabled.

In the video I've successfully reproduced the bug two times by switching 
ttys at around 0:25 when you can see just the cursor shown and also at 
0:40 where you can see some garbage colors which came from vim.

You can also notice that sometimes switching from one to other displays 
some artifacts until it is refreshed.

I hope for :-).
