Comment (by kencu):

 I got this one.

 Yes, xorg-server-legacy now uses posix spawn. The plan is for me to add
 these to legacysupport, which is 99% done, rather than conditionalize
 xorg-server-legacy.

 For now, Tiger users must use xorg-server-1.18 which still uses the old
 Tiger-compatable method of launching the server.
