Yes I did not take a chance and I compiled all statically to have no 
initrd problem. You also have XEN_DEBUG_FS, but it should not hurt.
If I remember well, the error is:

drivers/built-in.o: In function `do_hvm_suspend':
/mnt/tmp/linux-2.6-xen/drivers/xen/manage.c:124: undefined reference  to 
`xenbus_suspend'
/mnt/tmp/linux-2.6-xen/drivers/xen/manage.c:138: undefined reference  to 
`xenbus_resume'

These 2 functions are in drivers/xen/xenbus/xenbus_probe_frontend.c, and 
you have :
CONFIG_XEN_XENBUS_FRONTEND=m

On my side, I have:

CONFIG_XEN_XENBUS_FRONTEND=y

I think this could explain. There is a maybe a dependency problem in 
CONFIG_*:
- the code here (where the compilation fails) is for CONFIG_PM_SLEEP: 
have a look at the code in drivers/xen/manage.c, the section is in a 
"#ifdef CONFIG_PM_SLEEP" section.
- So if CONFIG_PM_SLEEP is set, CONFIG_XEN_XENBUS_FRONTEND should be 
compiled statically, and should not be set as a module in config kernel 
(make menuconfig bug ?)
Am I wrong ? Maybe ! I am not a kernel hacker !
