Unresolved symbol in module r128_drv.o

[julius ross <juliusross@mac.com>]

Hi,

I have found myself with a very flakely x-server (it crashes a lot when 
running certain applications e.g. gecko).  The only error in the 
XFree86.log I can see is

Symbol drmR128TextureBlit from module 
/usr/X11R6/lib/modules/drivers/r128_drv.o is unresolved!

I cannot think what I have done to cause this problem (it could have 
started after an apt-get upgrade).  I have debian sid with
xserver-xfree86 4.2.1-6
xfree86-common  4.2.1-6

Does anyone know how to fix this?  Or if I can downgrade to a working 
version of X?

Thanks for any help

Julius
