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

Detailed Monitor Information

radeonfb: Monitor 2 type no found
radeonfb: ATI Radeon Yd DDR SGRAM 128 MB
radeonfb_pci_register END
bound device '0000:01:00.0' to driver 'radeonfb'


and then


hStart = 664, hEnd = 760, hTotal = 800
vStart = 491, vEnd = 493, vTotal = 525
h_total_disp = 0x4f0063 hsync_strt_wid = 0x8c02a2
v_total_disp = 0x1df020c vsync_strt_wid = 0x8201ea
pixclock = 39721
freq = 2517
post div = 0x8
fb_div = 0x59
ppll_div_3 = 0x30059
lvds_gen_cntl: 08000008
Console: switching to colour frame buffer device 80x30


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:

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.
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...
