kmod: compiling with old sed version (!ERE support)

  Makefile.am uses `sed -E', which it is found on BSD sed; however a
  replacement on GNU sed would be `sed -r'. Both intend to use extended
  regular expressions (ERE). However I have a system that does not support
  those, in benefit for portability could you consider replacing ERE by BRE.
