problem being, that the bad patch that was identified in the first post:

 Author: Roland McGrath <roland@...hat.com>
 Date:   Sun Dec 23 12:47:41 2007 +0100

    x86 user_regset math_emu

    This converts the ptrace/signal accessors for i387 math_emu
    state to the user_regset interface style, and calls these
    from the old interfaces.

is only included in x86.git AFAIK. Maybe this commit is not really the 
culprit?
