I like the idea, but I think I'd prefer to tackle that at the same time as generic support for handling MSRs at RESET/INIT. E.g. instead of manually writing vmcs.GUEST_SYSENTER_* at RESET, provide infrastruture to automagically run through all emulated/virtualized at RESET and/or INIT as appropriate to initialize the guest value.
