Ok. I got the code (it is mvista, not mivsta...). My card is
recognized without modifications:

Console: switching to colour frame buffer device 80x30

--8<----8<----8<----8<----8<----8<----8<----8<----8<----8<----8<----8<--

Then, when changing to 1280x1024, with command

/usr/sbin/fbset  -depth 32 1280x1024-60

the actual console changes correctly, but when switching to other VCs,
the monitor again complains saying it gets bad frequencies: 103.1 kHz
horizontal and 197.8 Hz vertical.

If I blindly login, and run the appropriate fbset command, the
terminal works OK. I made this small script:

#!/bin/sh
stty cols 160 rows 64
/usr/sbin/fbset  -depth 32 1280x1024-60
consolechars -m iso15 -f iso15graf-16

and gave it a very short name. This way, once the terminal is set, I
can see what I type. I still have to logout and login again because
bash does not change its idea of the number of columns with
stty... So, quite uncomfortable but working ok. 

Obviously, if I were able to set the default mode to 1280x1024, things
would be sunny.
video=radeonfb:1280x1024-32@60 
and
video=radeonfb:mode:1280x1024-32@60 
seems not to produce any visible effect. What is the current proper
way to initialize radeonfb from LILO? 

And on a similar topic, could you write a couple of examples about how
to use the parameters included in radeon_base.c? I am thinking
especially of the "mirror" and "monitor_layout" parameters, that I
believe would allow me to use the two or three video outputs of the
card independently. I currently read

0 ATI Radeon Yd 

in /proc/fb. I should read two or three lines there, I believe...
