As mentioned elsethread, you are overriding the path by using 210.  That 
is to say, you are setting the current working directory.  The current 
working directory is used for opening files with relative paths (in a 
few different operating systems, even).  If you don't want to do this, 
don't do it. :)

Otherwise, you could try hacking away at the 
com32/lib/sys/module/common.c file and the findpath() function and find 
out if that helps you for your _post_-ldlinux.c32 phase, and simply 
hard-code the LDLINUX macro in core/elflink/load_env32.c for the 
pre-ldlinux.c32 phase.
