PPC guide should not in the same section where it tells users how to enable kernel drm support for Rage128/Radeon cards that xorg dri suppport is VERY VERY broken for at least some Rage 128 cards. Leads to corrupted xorg "screen" (video/mouse/keyboard issues/lockups) and r128 driver errors in Xorg.0.log: (EE) R128(0): R128CCEWaitForIdle: (DEBUG) CCE idle took i = 1025 (EE) R128(0): Idle timed out, resetting engine... Errors cease to appear and X functions normally once dri is diabled in Xorg or drm kernel module is not loaded. Problem exists in modular X as well. http://pastebin.com/496673 shows a full Xorg.0.log
None of this is particulary relevent.

I've never seen this behaviour, have you reported this problem upstream?
Can you attach your X.org config as well? Thanks!
Created attachment 76686 [details] xorg configuration attaching my xorg.conf This configuration is the same as what was locking up except I've now commented out loading the dri module and the DRI section. Had also tried not loading other X modules, none of which affected the situation and all of which load now with no problem.

Does it happen with stable X.org instead of modular? Have you reported the issue upstream yet?
Same problem occurs with mono X. Filed bug upstream, occurs in xorg 6.9.0 on Debian unstable as well. https://bugs.freedesktop.org/show_bug.cgi?id=5562
