i see. doing a little research i discovered sort of the same things,  
reading about people doing video stuff with pIII machines.
well, what's weird is that supercollider is saying the same thing  
when i try to boot a server, it shows up for a second in qjackctl  
then dies.
if i boot in a regular non-rt non-planet kernel, my regular hardware  
shows up at least, the intel 810 set. same problem with SC though.

anyway. is there a relatively easy way (command wise) to reinstall  
the entire fc6 and keep my home directory? or reinstall the entire  
thing and not keep /home and then just copy what i need from  
or wait to do that with fc7...?
or get a new machine one of these days?
