There was something braking my thoughts. Dont really know now what I was 
going to say :) I'll get back to that if it comes to mind.

There is no /etc/modules file in FC but there is rc.modules in which I 
have matroxfb.

I have a self-built cable also.

My typo, I ment PIII 550 :)

I have to test this out. top shows that its vdr that takes all the cpu 
but I hav to use one of the methods you mentioned to check the real reason.
