 I'm seeing this on an i386 machine running the tip of the netbsd-5 branch.
 
 Is there any chance anyone knows for sure what the exact fix was, and if
 it would be possible to pull that fix up to the netbsd-5 branch?  (I can
 easily patch and update the kernel for this machine, but much less
 easily update the whole OS at this time.)
