I need some ownership changes made to xorg-* and kernel packages.  When we
merged bugzilla components last week, we also switched from using a list
maintained internally that tracked ownership to owners.list.  Along the way, the
kernel and xorg packages lost their proper owners.  The owners are mailing lists
which the maintainers use to help triage bugs as they come in.

xorg-* needs to be assigned to xgl-maint
kernel needs to be assigned to kernel-maint

I'm attaching a patch that can be applied to the current owners.list to make
this change.  Thanks!
