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'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 ?

radeonfb doesn't currently have any code to post secondary x86 cards
so they won't work unless they have been posted by the system bios.
