Undetected video card on xSeries 206m

[Federico Fanton]

Hi everyone!
I have a little problem with FC6 running on an IBM xSeries 206m machine..
I can't get Xorg to detect the integrated video card (Radeon 7000/VE)
using the ati driver, while with FC4 and 5 everything was ok..
The fbdev driver works though, but it's a bit slow.

Looking at the PCI scan, it seems like Xorg misses the device
completely.. My xorg.conf Device section:

---
Section "Device"
  Identifier  "Videocard0"
  Driver      "ati"
  VendorName  "Videocard vendor"
  BoardName   "ATI Radeon 7000"
  Option      "NoAccel"
EndSection

I tried to install a new video card (ATI RageXL), but it doesn't detect
it either.. What could be wrong?

Many thanks for your attention, please ask if you need more information!
