Xorg not running with ATI r128

[Arthur Grandi]

About an year ago I was able, with your help - https://forums.gentoo.org/viewtopic-t-1078182.html - to run Xorg with fdev and xterm and twm on my ibook G3 Dual with 324 Mb ram.

I have still not suceeded in running Xorg with ATI r128, in spite of the fact that i have being trying hard since then. I have managed to change the Xorg.0.log many times, by following errors, but I am now totally stuck with a Backtrace I can't understand. I still have twm and xterm.

Hoping for your wise ords I wgetpaste some info:
