Ahh, d'oh. I misread the x86 instruction set reference manual.

I'm actually seeing a failure on the elflink branch (after merging
master into elflink). The sscanf() call in
com32/lib/sys/module/exec.c::module_load_dependences() isn't working
properly, i.e. you get different results before and after the commit I
pointed out in my patch.
