Current xen-unstable bootup on a P4 doesn't get as far as
to start up domain 0, on my test systems.  The last line
it prints out is:

(XEN) mtrr: v2.0 (20020519)

I'm digging through the code to try and figure out what
function is called next, but mtrr_init (which displays
this message) doesn't seem to be called from anywhere.

Arch/x86/smpboot.c, OTOH, has calls to mtrr_init_boot_cpu()
and mtrr_init_secondary_cpu(), which aren't defined anywhere
and under CONFIG_MTRR, which in turn doesn't seem to be
defined ;)

"Debugging is twice as hard as writing the code in the first place.
Therefore, if you write the code as cleverly as possible, you are,
by definition, not smart enough to debug it." - Brian W. Kernighan
