There are bugs in some of the X drivers for karmic, 9.10.
I suggest you point your sources at the ppc cutting edge repository
for your particular graphics card.

I have been on 9.10 for a long time now, and CPU usage has gradually got better.
I don't really care for all the 3D gui stuff, so I generally use XFCE4
So, I think your 75% CPU is due to driver bugs, that are likely to be
fixed if you get the ppc repository.
