Try downloading http://xenbits.xensource.com/staging/xen-unstable.hg, and
build inside tools/firmware. Then use tools/firmware/hvmloader/hvmloader as
your HVM 'kernel' (what you specify as the 'kernel' in your HVM config
file).
If that doesn't help, then track down the crashing %cs:%eip inside vmxassist
(objdump -d tools/firmware/vmxassist/vmxassist) and we'll see if that shows
up anything interesting.
