There's many differences as the kernel is much older than what Fedora 10
is using. Maybe an older version of the video drivers? I don't know how
that could explain the problem... Or maybe a configuration option is
different (at the kernel build level) because there is something missing
in the older kernels and it defaults to something different. Weird.
