I've tried both patches.
The first gave me a kernel panic when I started firefox:
Unread portion of the kernel message buffer:
panic: vm_page_free: invalid wire count (2), pindex: 0x2

Backtrace stopped: previous frame inner to this frame (corrupt stack?)
The second patch didn't fix the issue as I've been able to successfully 
reproduce the problem after applying it.
I've uploaded kdump output from a failing firefox proccess at
