Xen users - Dec 2008 - A x86_64 processor can not run a x86_64 HVM

I own an Athlon 64 X2 Dual Core Processor 5200+. I enabled SVM extensions on
BIOS. I did a power cycle.

xm dmesg shows me:

(XEN) AMD SVM: ASIDs enabled
(XEN) HVM: SVM enabled
I run a 64 bit Xen kernel (OpenSuse 11). Xen version is 3.2.1_16881_04-8.6

I _can not_ run any x86_64 O.S on a HVM domU, because it appears something like
this: "your cpu does not support long mode. use a 32bit distribution."
Using 32 bit distros, it works but I would like to use 64 bit O.Ses.

Thanks

What s the output from 
# xm info | grep caps
hw_caps                :
178bf3ff:ebd3fbff:00000000:00000010:00002001:00000000:0000001f:00000000
virt_caps              : hvm
xen_caps               : xen-3.0-x86_64 xen-3.0-x86_32p hvm-3.0-x86_32
hvm-3.0-x86_32p hvm-3.0-x86_64

you need this hvm-3.0-x86_64

This is the output of xm info | grep caps command:
hw_caps : 178bf3ff:ebd3fbff:00000000:00000010:00002001:0000000:0000011f

hvm-3.0-x86_64

Thanks

This is the output of xm info | grep caps command:
hw_caps : 178bf3ff:ebd3fbff:00000000:00000010:00002001:0000000:0000011f
xen_caps : xen-3.0-x86_64 xen-3.0-x86_32p hvm-3.0-x86_32 hvm-3.0-x86_32p
hvm-3.0-x86_64

Can some one help me? I think it can be a Xen bug, because I tried it
with Ubuntu Hardy Heron 64 bit and I get the same error.

Thanks
