When loading the radeon driver into pre-release X:

XFree86 Version 4.2.99.2 / X Window System
(protocol Version 11, revision 0, vendor release 6600)
Release Date: 14 November 2002

Monitor fails to sync and console is lost. I can still get into the machine 
fine via SSH, is this known?

Can't use ksymoops (busted compile with binutils 2.13.90.0.10 20021010 and  
GCC 3.2.1 20021118 (prerelease))

Can't use kksymoops as its commented out in Kconfig (i386 arch) ;-) and it 
doesnt seem to work uncommented ;(
