in my SVGA section:
Device "NeoMagic (laptop/notebook)"
in the fbdev section:
Device "Generic VGA card"
using XFree86_FBDev as a server did not work with these settings.
Workaround: replace the "generic" line with the "neomagic" line.
I don't think that changing the device is the right way to fix this.
What laptop, and were you using 6.2 final?
Neomagic cards should work correctly without attempting to use the framebuffer,
so I close the bug.
This might be related to one of the prereleases which did use it.
