I guess no one paid any attention to my previous post several days ago
regarding this problem. The cause of the crash was that wine expected
fs to be the same as ds initially, but this is not the case on FreeBSD.
Fs is set to cs instead. There are two solutions.
1. Set fs to ds in the kernel,
2. Initialize fs to ds at the very beginning of wine, before any call
   to the scheduler module.
