I had the same problem a while back with my SuSE 9.0 installation. At 
first I also thought the problem was KDE related.  But after upgrading 
3.2 to 3.3 the problem still 'hung' around. I realised I still had the 
network running, which enabled me to notice that  X was locked up / 
using 98% of my CPU. Sending a SIGKILL helped X restart but f*cked up my 
console display, only a reboot would fix that. The X version info showed 
that it was the 4.3.0.1 Pre-Release version.  Upgrading X solved the 
issue for me.

On another box I had arts making a mess, I had xmms with OSS plugin 
running instead of the arts plugins, this somehow froze the box 
everytime the arts deamon tried to throw a 'system sound' @ the 
soundcard. Getting xmms to work with the arts-plugin solved that issue.

Maybe the info helps...
