Recent Intel driver and the latest xorg (not yet released) and 2.6.28
kernel has new memory management GEM which address slow performance for
intel graphics. It is not bug in ubuntu 8.04 and 8.10.

7.xx ubuntu is fast because there were intel driver with TTM memory
management which was droped by intel (in flavour of GEM).

You have to wait for ubuntu 9.xx (I hope there will be new intel driver)
or you have to compile xorg/kernel/intel by your self which is not an
option for usual users. Or go back to 7.xx ubuntu.

I've 400 fps in ubuntu 8.04 and 1150fps in ubuntu 8.04 with new
xorg/kernel/intel driver. There are still major 2D performance issues
when compositing and others have reported slow 2D -
