[Bug 221119] Re: [gutsy, hardy, intrepid] Blank screen and (EE) intel(0): overrun on pipe B! on i945GM using intel driver

I've got problems too. My editing with Netbeans has become really bad
because when scrolling or doing some other operations there's too much
lag. Looking at 'top' on shell I see that Xorg raises up to 90% of
cpu... that's not acceptable.
