I'm having the same problem installing Xfree86-4.1.0-16 on a Dell
Latitude CPi D266XT as described by Brian Kendig (see below).
I was able to get around the problem by adding these two lines to
'/etc/X11/XF86Config-4':
Option "XaaNoScanlineImageWriteRect"
Option "XaaNoScanlineCPUToScreenColorExpandFill"
But those are the same two lines you said you added, so I don't know
why they're not working for you. Make sure you're adding them to the
Device section which configures your video, and make sure you're
selecting the "neomagic" driver.
Something else, too -- your laptop's display can handle up to 1024x768
at 16-bit color, but if you use 32-bit color, then you can only handle
up to 800x600. Make sure the 'Depth' and 'Modes' lines of your Screen
section reflect this.
I'm running Debian unstable now, and I no longer need those Option
Xaa... lines in my XF86Config-4 file, so it looks like the bug has been
fixed in the latest XFree86.
