I've added

What about reading the docs? http://www.mediawiki.org/wiki/Manual:$wgNamespaceProtection /If you list more than one permission for a given namespace, a user must have all of them to edit pages in that namespace./
The solution is to place only bsv in $wgNamespaceProtection and give the sysop group the bsv right.
($wgNamespacePermissionLockdown works the other way, user must be on *any* of those groups)
