I have to disappoint you, unfortunately. SuperTux on my PCI Radeon
stalls everything that e.g. tries to access the hdd. However, when
I lower the X server's priority, the hdd access gets smooth during
SuperTux, but the screen that the game runs on starts developing
some interesting effects, like dragging the whole screen back, i.e.
in the opposite direction where the scrolling goes and it does it
regularly, causing nasty flickering.

However, I experimented with Con Colivas' scheduler and it seemed to
solve most of this. I expect Ingo Molnar's realtime work will solve
this totally.

Yes, there are, I thought about that, too.

These are clear advantages. :-)
