TFT goes into suspend with radeon driver

[Alex Schuster]

Hi there!

I cannot get X to run on a friend's machine I just upgraded. That is, I do 
not get any errors and probably X is running fine, but the display goes 
into suspend mode immediately. I replaced the TFT with a CRT monitor, and 
it also shows nothing and complains about bad frequencies. It happens both 
with and without xorg.conf. And also with the radeonhd driver, but that is 
not suited for this graphics adapter. With vesa, the same happens, and 
additionally the system freezes, I cannot switch to a text console (even 
after Alt-SysRq-R). fglrx is no longer an option with this card.
I am out of ideas (apart from replacing the graphics adapter), and hope you 
can help me. Any insights are greatly appreciated.

The system runs an up to date Gentoo Linux. These are the specs:

Software versions:

x11-drivers/xf86-video-ati-6.12.4 (also tried 6.12.1-r1)
x11-drivers/ati-drivers (fglrx) is not installed as it does not work with 
this card, so no fglrx.ko module is loaded together with radeon.ko.
