I thought I checked for that, but I must have overlooked it.

It causes additional "things" to be loaded. Based upon its name, 
I assumed it was "really" so that kernel modules could be loaded
at boot time and that the xen team found it met their needs and 
used it.  Xen is basically a hypervisor, and to boot you need to
you need to load 3 things: the hypervisor, the corresponding Linux
kernel (ported to the hypervisor) and its ram disk. 

I grabbed the grub source to take a look at exactly what it does, 
where it puts things, how it tells the "kernel" where they are, etc.
but I haven't gotten that far yet, and with luck (and your help) 
I won't have too.  :-)  Sorry I don't have more technical information
than that.

Thanks much,
