loading /boot/kernel's modules when a different kernel has no modules,
but you left your module_load="YES" in loader.conf...

we construct the EFI image. It doesn't seem to actually end up
in the EFI image, AFAICT.
o Replace .quad, .long and .short with data8, data4 and data2 resp.
The former are gnuisms.
o Redefine _start_plabel as a data16 with @iplt(_start) as its
value. This is the preferred way to create user PLT entries.
binutils 2.15. The linker now creates a .rela.dyn section for
dynamic relocations, while our script created a .rela section.
Likewise, we copied the .rela section to the EFI image, but not
the .rela.dyn section. The fix is to rename .rela to .rela.dyn
in the linker script so that all relocations end up in the same
section again. This we copy into the EFI image.

This lets you PXE boot with a GENERIC kernel by putting this sort of thing
in loader.conf:
bootp="YES"
bootp.nfsroot="YES"
bootp.nfsv3="YES"
bootp.wired_to="bge1"

null-terminated, and the sprintf that was used would copy up to the
next null byte, which could be pretty far away.
