[ltp] Starting of second x-server: DRI fails

[Florian Dorpmueller]

After some trials I managed to eliminate "(II) RADEON(0): [drm] drmSetBusid 
failed (6, PCI:1:0:0), Device or resource busy". For that I deactivated DRI 
for the first X-Server.

Trying to start the second one no gives me:

(WW) RADEON(0): Failed to set up write-combining range 
(0xe0000000,0x2000000)

And finally:
(II) RADEON(0): Direct rendering disabled

Maybe anyone has some hints for me?
