Actually, I did the same thing last night:

http://people.freebsd.org/~jkim/patch-src-VBox-Runtime-r0drv-freebsd-memobj-r0drv-freebsd.c

This is a drop-in replacement for the patch.  The only practical 
difference I see from yours is I used VM_ALLOC_INTERRUPT instead of 
VM_ALLOC_NORMAL.  I believe this function may be used in interrupt 
context.  FYI, I tried FreeBSD 9 and Fedora 10 without problem.
