Here are some step-by-step instructions on how I upgrade modules from d6 to d7:
drush dl coder
drush dl grammar_parser
drush en coder_upgrade
put the latest 6.x version of the module into sites/mediatribe.net/files/coder_upgrade/old
go to admin/config/development/coder/upgrade
click the checkbox next to the name of the module you are upgrading to d7
click convert files
make sure there are no error messages
click on the module name
now you are looking at the patch
get the latest 6.x CVS version of the module into sites/all/modules
