My mistake. I could have sworn the original d-d-a announcement had a
Reply-To: debian-cd, not debian-devel. I will also file a bug soon.

Thanks. My version was pretty close to win32-loader's cpuid.c, but
that one had a few extra precautions, so I'll grab from there. A new
version is attached (also at
http://www.finnie.org/software/debian/devel/syslinux-menu-default64.patch).
And to avoid a bit of confusion, the functionality isn't /exactly/ the
same as the old autodetection patch. The original
02-64bit-autodetection.dpatch logic was "if the user presses Enter,
boot this section if it's 64-bit, otherwise boot this section". The
logic for the new menu patch is "if it's 64-bit, highlight this menu
entry for the user, otherwise highlight this menu entry", which is
more in line with the concept of the menu (and easier to implement).
