In drivers/xen/blkback/xenbus.c, the function backend_changed exclusivy job is
to read those values. Here is an example:
278 err = xenbus_scanf(XBT_NIL, dev->nodename, "physical-device", 
"%x:%x",
279 &major, &minor);
I would recommend you get a copy of "Understanding Xen" to understand how
XenStore "transfers" the data from one domain to another.
