here patches for -current and releng_7:
http://78.107.232.239/rt_signals-current.patch
http://78.107.232.239/rt_signals-releng_7.patch

what patch do:
- rt sigtramp code works (this solves PR)
- align stack pointers
- remove kern_sigaltstack() at the end of rt_sigreturn(), it's a bogus.
   Here there is some information on it:
