Well, I just tried the intel driver using up to date rawhide and the problem is even worse (60% CPU usage to scroll 60 lines per sec... that's 28 million CPU clock cycles per line printed). If I reduce the window size to one line, the CPU load goes down to about 30%, or 14 million clock cycles per line or ~140,000 clock cycles per character printed. Something ain't right. This was with no xorg.conf which uses the intel driver with default settings I guess. Cheers...
