Ugh. You have the vga16, vesa, and NVIDIA framebuffer drivers enabled. 
The NVIDIA driver might not work with your card. The VESA will so you 
should only enable that. Also you enabled both VGA console and frmaebuffer 
console. Please only enable framebuffer console.

Hum. Like to see those bugs.

vga=791 will not work for the rivafb driver. That is vesafb specific. You 
need to use modedb. See linux/Documentation/fb/modedb.txt.


P.S
   I think the modedb code is broken for the NVIDIA driver. I haven't got 
around to fixing that.

Strange. I will see if I can duplicate this bug. Is the bug at boot time 
or is it present all the time?

All the time.

Everything looks fine at the beginning, but running i.e. 'top' causes the 
console is unreadable. I can make it readable for a while with simple 
switch between consoles.

I don't know if I described it ok - the best would be short *.avi of that, 
but I don't have any camera...
