Since RELENG_7s GENERIC still comes with SCHED_4BSD I assume that you
still have the old one.

To be sure you can verify this by:

  % sysctl kern.sched.name

In your case it should be:

  kern.sched.name: 4BSD

To switch to the new you have to build a new kernel.

Pretty good described here:
http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig.html

Just be sure to replace

  options         SCHED_4BSD              # 4BSD scheduler

With

  options         SCHED_ULE               # ULE scheduler

In my case it resolved some mouse and audio problems under X.Org.
Don't know if evolution is affected, too, but you can give it a
chance anyway.
