Comment 5 for bug 407587

I'm not sure if it's the same bug but I've just installed today's (2009-10-05) Kubuntu Karmic cdimage on i865G hardware and since boot from LiveCD til now (installed and upgraded system on hard drive) I'm getting proper display on intel driver but Xorg eats ~100% CPU and even text typing in Konsole lags so much as it looks like working on SSH terminal on heavy loaded server/internet connection - letters are arriving few seconds after typing them. But when I switch to console (CTRL+ALT+F1 the Xorg doesn't eat even 1% CPU and system is very responsive and I've get ~99% CPU idle). After switching back to KDE4.3.1 in Xorg (ALT+F7) there's ~100% CPU eaten by Xorg etc. So I've installed Kubuntu by most of the time switching to console to idle the CPU. Is there any workaround for this - other than switching to Vesa driver?
