Sorry for the delay. The issue happens on someone else's computer, and I
get to use it for about two days every two months, so it's a bit hard
for me to answer quickly with new information. Right now I'm using this
computer again, until tomorrow night :)

The computer is effectively using Ubuntu Lucid Lynx, and the issue is
still there. As an example, when I open System Monitor in GNOME, the
processor's activity graph shows always 100%. Then I swtich windows and
do something else in the console, for example, and then come back to the
System Monitor. Now the graph shows the processor's history was not
always 100%, but now that I'm looking at the graph and it's being
redrawn, processor is again at 100%.

The other example is the one I talked about in my initial report. If I
open a gnome-terminal and look at ``vmstat 1``, cpu's idle time is
constantly around 50%. If I start moving gnome-terminal's window around,
idle time suddently changes to a constant 0.

I think there's a problem with redrawing which is eating the processor
and not using the video card properly. If that's the case, this bug
might be easy or really hard to fix. If the problem is a setting in
Xorg's conf file, then it'll be easy. But if the problem is the kernel
has no good support for this card, then I guess this is almost a lost
case, since the card is really old and pretty likely no one will ever
attempt to fix this.

Thanks,
