Rage128 + XFree 4.2.0

[Hynek Rehor]

Hi,

i am trying to install new XFree 4.2.0, but my Rage 128 DRI mode doesn't 
work. Here is copy of XFree log:

........ cut ..........

II) R128(0): Starting up Xvideo subsystems
drmOpenDevice: minor is 0
drmOpenDevice: node name is /dev/dri/card0
drmOpenDevice: open result is 6, (OK)
drmOpenDevice: minor is 0
drmOpenDevice: node name is /dev/dri/card0
drmOpenDevice: open result is 6, (OK)
drmOpenDevice: minor is 0
drmOpenDevice: node name is /dev/dri/card0

drmGetBusid returned ''
(II) R128(0): [drm] drmSetBusid failed (6, PCI:1:0:0), Permission denied
(EE) R128(0): [dri] DRIScreenInit failed.  Disabling DRI.
........ cut ...........

I dont't understand the line with 'Permission denied'. What does it mean 
? With previous 4.1.0 everything works fine. I use 2.4.18-pre7 kernel, 
agp support as a module, dri drivers and XFree drivers from 
gatos.sourceforge.net, experimental 6.
