Meaning that it's fast and good if there is a driver for the used card and a 
bit useless if there isn't?

Ah, ok. I'll have a look. Back then DFB didn't really move at all, I think it 
was stuck on the same release for half a year or something, and the 
mailing-list I was on was dead for months.

I meant that it felt heavy and slow. Sure it is lighter when looking at raw 
software, there is just so many layers less and so much less memory used, but 
still X felt snappier at drawing stuff.

But, I'll believe someone who actually uses in and give it try. Thanks for the 
encouragement. :)
