Hi Robbert, 

Thanks for the debug info.
I just tested the FF4 on my box. It does not crash. My box is AMD64
Current too. (it's a bit more "current" than yours)
  
# uname -a
FreeBSD crystal-coding.com 9.0-CURRENT FreeBSD 9.0-CURRENT #6 r219859:
Tue Mar 22 16:20:56 EDT 2011
omg at crystal-coding.com:/usr/obj/usr/src/sys/MYKERNEL  amd64

mind sync your world a bit?

Best, 
 Glenn Chen
