here are 2 new patches containing the discussed issues.
- opt_feature_linux.patch
  implements the usage of the hypercall from dom0/domU
- opt_feature_xen.patch
  for PV: implements the new hypercall  __HYPERVISOR_opt_feature.
  for HVM: does this in set_os_type().

I added 3 features:
  OPTF_IDENT_MAP_REG7, OPTF_IDENT_MAP_REG5, OPTF_IDENT_MAP_REG4

Please send comments or commit!
Thanks.
