[issue871] gtk2 related: X mouse pointer jumps and sticks to top left corner

[Matthew Dillon]

:I tested this patch (I'm also another one, who got his mouse stuck in X) and I
:get _many_ messages from firefox "kernel: pid 1158 (firefox-bin) signal return
:from user: illegal FP MXCSR ffff0010" (the message repeats and does not
:change) and the firefox process itself seems to be stuck, eating up as much
:CPU as it can, but doesn't do anything.

     Update /usr/src/sys/kern/subr_prf.c to the latest, which fixes krateprintf().
     You will see only one message / sec then.

     When I test this, the non-GTK firefox seg-faults but the GTK firefox does in
     fact seem to work.  The non-GTK firefox seg-faults even without the FP changes
     so I don't think they made things worse.

     firefox-gtk1-2.0.0.8 seems to work.
