Are the K6-CPUs powerfull enough for playing ut2k3 at an acceptable framerate? 
If no then I'd not support them anyway. It's a bit like you would drop any 
pentium-feature to make it run on a 486 :)

Yes it is, My celeron800 makes the game unplayable on linux, works more or 
less on windows though (feels about 10fps faster which makes a difference on 
this sys!).

I'll have a look a t OpenAL CVS and see if I can compile it and then bench 
again with what I compiled.
