Dear Benjamin Herrenschmidt, dear mailing list subscribers,

     I'm trying to load radeonfb for an RV100 QY chipset. Whatever I
type in the modprobe I always get:
       radeonfb (0000:01:0c.0): cannot map FB
       radeonfb: probe of 0000:01:0c.0 failed with error -5

I suspect your BIOS isn't initializing the secondary card, radeonfb is
thus unable to use it.

However, you probably don't need radeonfb. X.org should be able to get
it going as a secondary just fine, but your text consoles will have to
remain on the intel.

In the long run (though it might already work with latest upstream), the
new radeon KMS should be able to initialize those.

Cheers,
Ben.

    I've tried latest 2.6.27.x and 2.6.30.x kernels. This a secondary
video card that I would like to connect a monitor to. The first video
card is an Intel 915G, which is working with vesafb.

    Here is the output of lspci -vvv

    Can you or anyone give a hint on what I might be doing wrong:
modprobe radeonfb mode_option=800x600-16 panel_yres=600
    Or could this be some kind of hardware issue ?

    Thanks a lot for your help,
