We have test latest xen on VT platforms with Intel 915/E8500 chipset.
Can't create any version of VMX guest on both IA-32/IA-32e mode platform. 
IA-32: 
 Build&Boot SMP xen0 without problem ( builder is gcc 3.4.2/Fedora Core 3)
 Can NOT bootup unmodified 2.4/2.6 linux on VMX domain 
 Can NOT bootup unmodified Window XP on VMX domain
 Can NOT bootup VMX & XenU with different configuration
 
IA-32e: 
 Build&Boot SMP xen0 without problem (builder is gcc 3.4.3/RHEL4u1)
 Can NOT bootup unmodified 2.4/2.6 IA-32 mode linux on VMX domain 
 Can NOT bootup unmodified 2.6 IA-32e mode linux on VMX domain 
 Can NOT bootup unmodified Window XP on VMX domain
 Can NOT bootup IA-32 mode VMX & xenU with different configuration
 
issues:
 - VMX guest hang in booting up on IA-32 service OS, if XEN was builded in 
gcc 3.4.2/FC3 system.
 - Fail to create VMX guest on IA-32e mode service OS.
 - Fail to create 32-bit windows domain.
