Getting a chance to look at this again...
md5sum for Intel3.5/EFIX64/E3507X2.EFI matches.
build command line matches.
qemu version 1.2.0
qemu: I've had better success with the default console (instead of vnc)
If I add -s -S to the qemu command line and attach it to gdb:
$ gdb
...
(gdb) target remote localhost:1234
Remote debugging using localhost:1234
0x0000fff0 in ?? ()
(gdb) cont
Continuing.
the console title will change from "QEMU [Stopped]" to "QEMU", but nothing
appears on the screen...
At this point I'd like to use gdb to poke around but probably need some
symbols. Andrei Warkentin's blog here

helpful but his source (
https://github.com/andreiw/andreiw-wip/tree/master/uefi/DebugPkg) is out of
date... I'm getting:
build.py...
/home/duanev/efi/edk2/AppPkg/AppPkg.dsc(...): error 4000: Instance of
library class [DxeServicesTableLib] is not found
in [/home/duanev/efi/edk2/AppPkg/Applications/GdbSyms/GdbSyms.inf]
[X64]
consumed by module
[/home/duanev/efi/edk2/AppPkg/Applications/GdbSyms/GdbSyms.inf]
when I drop his GdbSyms into AppPkg. I don't understand the build
environment yet - AppPkg/Applications/Sockets/WebServer also
uses DxeServicesTableLib but compiles fine and I can't find any differences
between the .inf files that might cause this. :P
