Re: radeonfb doesn't work with an ati X800 pcie card

[Jimmy Jazz <Jimmy.Jazz@gmx.net>]

I made some more tests and without forcing the monitor type. I get some 
odd results and quite the opposite of what i was expecting.
Ignoring the connectors table is not a great idea.

The monitor, a dvi flat panel wide screen (1680x1050), is connected to 
the first video card connector with a dvi cable. Instead, the radeonfb 
driver sees a CRT connected to a vga connector. Heeelp !

when i don't ignore the connectors table, the dvi connector is well 
defined but the monitor is not.

I can't believe i'm the only one who isn' able to use an "old" x800 pcie 
card connected to a dvi flat panel. Get rid of the boring 640x480 
resolution dictatorship and have a nice splash screen, that my moto ;)

If someone has any clues, he is very welcome.
