and for those users using browsers that submit forms with the "enter" key,
they're probably used to that behavior.

if they're used to the default behavior, why would you want to take that
away?  what if they have javascript disabled?  then what?

suggestion -- forget about the "enter" key entirely.  if you don't want them
to submit the form early then use the onsubmit event handler to validate the
form and halt submission if it's insufficient/invalid.

function validateForm(form)
{
  if(!form.username.value)
  {
    alert('Username is required.');
    form.username.focus();
    return false;
  }
  if(!form.password.value)
  {
    alert('Password is required.');
    form.password.focus();
    return false;
  }
  return true;
}

and called from the onsubmit event handler like this:

<form
 action="login.cfm"
 method="post"
 onsubmit="return validateForm(this)">

good luck,
