# uname -a
NetBSD  5.0_BETA NetBSD 5.0_BETA (XEN2_DOMU) #0: Tue Nov  4 00:34:57 PST 2008  
builds@wb40:/home/builds/ab/netbsd-5/i386/200811030002Z-obj/home/builds/ab/netbsd-5/src/sys/arch/i386/compile/XEN2_DOMU
 i386

so I'm sure it's this one. I got:
VIRTUAL MEMORY ARRANGEMENT:
 Loaded kernel: c0100000->c04dab54
 Init. ramdisk: c0544000->c0544000
 Phys-Mach map: c0544000->c0554000
 Page tables:   c0554000->c0557000
 Start info:    c0557000->c0558000
 Boot stack:    c0558000->c0559000
 TOTAL:         c0100000->c0800000
 ENTRY ADDRESS: c0100000

There is a large difference in the Phys-Mach map between yours and mine;
I guess it's because you're using a different initial amount of memory.

Attached is a xen.gz kernel build with debug functions. Could you try with
it ? Maybe you'll get some infos on serial console or 'xm dmesg'.
