FPC and FESCo recently approved packaging guidelines for initscripts http://fedoraproject.org/wiki/Packaging/SysVInitScript . According to those guidelines only services which are really required for a vital system should define runlevels as the first parameter on the '# chkconfig: #' line in the initscript. Please consider changing the initscripts in the wine-core package.
Changing version to '9' as part of upcoming Fedora 9 GA. More information and reason for this action is here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
Since wine only adds a bin format handler I guess it is ok to have it on by default.
