That might make more combinations available to Xen and provide more detail. The messages are coming from Xen before it even loads the Linux kernel, but yes- a newer version of Xen such as in R4.1 might also help. If you have a serial port available, you can set Xen to log to it, but that is often a hassle with newer machines.
