I built a kernel off of revision 286315 and got this:

	eris% objdump -R kernel | grep FPTR64LSB | wc -l
	    5377

We only reserve room for 4096 relocations, so we’re over
as it is.

A kernel off of revision 286316 gave me this:
	eris% objdump -R kernel | grep FPTR64LSB | wc -l
	    5377

Same. Odd, but ok. It’s possible that the memory layout
changed such that we now scribble over something that’s
important.

To be sure: Anton can you apply the following patch and
tell me if it makes a difference. It doubles the space
we set aside for relocations.
