That's odd.  I'll look into it.  it could be a problem with one of the
accel routines, some of them seem to have issues on crtc2.  you might
try turning them off to see if one is causing the problem.  I've had
reports of ScreenToScreenCopy causing problems on supersavages on
crtc2.

not sure. I haven't had any problems in that regard.

shadowstatus causes this on some systems if the DRI isn't enabled as I
recall.

there is no clone option in the driver.  You can safely remove it.

I actually have it coded up and working, there are just some mode
swiching bugs that need to be sorted out, plus I need to merge it with
the latest cvs code.  One of these days I'll get it finished up.  It
will of course be annouced on this list when it's done.  If there is
interest, I can but a tarball up, however, it's still based on the old
drm, so it won't work with the new drm or mesa driver until I merge the
latest cvs changes in.
