If you specify the full path instead of browsing to the directory, it
should work.  When linux programs ask for files, the kernel first looks
in /compat/linux/, then /.  

If you need to be able to browse to files, you can try null mounting /
and /usr into /compat/linux/realroot, then browse through that.  Or, if
you have amd enabled, browse through /net/localhost/...
