    The X server in unstable is expected to not work without the patch. It should
    behave the same as the kernel in testing in this regard.

    That's strange, because others report that the patch fixes the problem. I'm a bit
    lost now and it's difficult to further debug this without the proper hardware.
    Are you really sure that you are running the patched kernel and that you are
    not running the kernel from lenny or unstable?

    I run kernel that I downloaded from your site. May be problem is that E250 i multi domain PCI machine.
    Have other people the same HW as I or eg. Ultra 10 or 5 ?
