iBook x config

[nicole]

If he finds something that works, please post about it.  I had the 
2.6.6 kernel and have the "torn" affect you describe... compiling CVS 
helped enough that my display is mostly useable. I have tried the 
chipset id variable with no success.  Currently my display is useable 
for about 5 - 10 minutes before headaches ensue from the "scrolling 
line" effect.  I am trying to get this to work though at this point I 
am ready to try another distribution.  I got my iBook in 11/03 so I 
suspect I do not have the older Radeon chipset this works on.
