Hmm, FreeBSD seems to choke when trying to load the
grub-bootstrapped mfsroot.gz (as the root device - haven't tried loading
without rooting from it)...
This is a custom mfsroot, booted like so:
menuentry "FreeBSD 7.1-STABLE amd64" {
freebsd /osstore/STAGE2/FREEBSD/amd64/kernel.gz Dh
freebsd_loadenv /osstore/STAGE2/FREEBSD/amd64/device.hints
freebsd_module /osstore/STAGE2/FREEBSD/amd64/mfsroot.gz type=mfs_root
set FreeBSD.vfs.root.mountfrom=ufs:/dev/md0
}
perhaps I'll try with the Sysinstall floppy's mfsroot - it might be a little
smaller.
PS. A correction for that last patch:
-MOSTLYCLEANFILES += bsd_mod-loader_i386_bsd.d bsd_mod-loader_i386_bsd.d
+MOSTLYCLEANFILES += bsd_mod-loader_i386_bsd.d bsd_mod-loader_i386_bsd_helper.d
Thanks

Figured it out,
s/multiboot_mod-loader_i386_multiboot_helper/bsd_mod-loader_i386_bsd_helper/
and bingo!
Worked ion both Xen HVM and on a real amd64 box (over PXE)
Yay GRUB2 and its devs!

I can't make grub2 build with phcoder's bsd64.diff. My guess it is beacuse conf/i386.mk is missing stuff related to
loader/i386/bsd_helper.S $(loader/i386/bsd_helper.S_DEPENDENCIES)?, but I wouldn't how or where to add it in.

Bean kindly allowed me to mess with this patch. So here comes an
improved version. I moved helpers out of the kernels. Because of how
FreeBSD expects the initial virtual memory mapping only first GB of
physical memory is accessible so it was required to use of trampoline
technique.
