Is this really true?

I mean, will the stub actually allocate seperate selectors with DPMI
for other sections, or just load all those sections into the same
virtual address space, as I thought?

I managed that... without changing the ld script, so ld just put my
section into a section of the same name in the output file (ie, didn't
group it). No need for different .ld scripts unless you want to
control the placement of this section in the load image.
