[erlang-questions] has anyone cross compiled HiPE?

Q1: Has anyone already managed to cross-compile HiPE for ARM?
Q2: Can someone give me a quick rundown as to how HiPE cross compilation
is meant to work?
Expanding the questions:
Q1: I just had a quick go at getting R15B to work on ARM. I have normal
Erlang (i.e. no HiPE) running on ARM; I cross-compile it from an AMD64
machine. Works fine.
But if I try to enable hipe, i.e.
./otp_build configure --enable-hipe --xcomp-conf=../erl-xcomp-armle-linux-gnu.conf
then the build bombs out partway through. It looks like it dies
when it tries to execute the ARM version of 'hipe_mkliterals'.
I could work around that, for instance by manually running
hipe_mkliterals on an ARM. But if someone already knows how to
get this going, then that'd be nice to know.
Q2: I figure I need two things to make HiPE work on ARM.
First, I need an emulator running on ARM with HiPE enabled. That's
what Q1 is about.
Second, I need to compile my Erlang code to ARM native code.
I can't see an option to do that, i.e. if I use c(my_module, native)
on my AMD64, I get an extra chunk in the .beam file called
"HA64". I'm guessing that's AMD-64 specific code. So I need some
way to tell HiPE that I want it to make ARM native code.
(I've looked at TFM, specifically the HiPE App and the compile
module page. Nothing there about generating code for specific
targets. Maybe there's another page I've missed.)
Or is the sane way to get HiPE on ARM to start with a native ARM
