Thats what I was thinking too, but when I grepped through the arm sources
I didn't really see that bootconfig struct being used for anything related
to UVM. It seems to be used in the acorn* ports, but for the
sys/arch/arm/ related code it seems to only be used in dumpsys(). As far
as I can tell, I'll still have to call uvm_physload() in my machdep
