You could use a directive to calculate the height of the form. It will recalculate on window resize. I haven't tested navigating away from the page.

Codepen

Relevant HTML

<ion-view hide-nav-bar="true" ng-controller="MainCtrl">
  <ion-content padding="true" scroll="false">
    <ion-scroll scroll-height>
       Content to go above the form
    </ion-scroll>
    <div class="login-form">
      Login form
    </div>
  </ion-content>
</ion-view>

CSS

.scroll-content {
  position: relative;
}

div.login-form {
  position: fixed;
  left: 0;
  right: 0;
  bottom: 0;
}

Directive

.directive('scrollHeight', function($window) {
  return {
    link: function(scope, element, attrs) {
      scope.onResize = function() {
        var winHeight = $window.innerHeight;
        var form = angular.element(document.querySelector('.login-form'))[0];
        var formHeight = form.scrollHeight;
        var scrollHeight = winHeight - formHeight;

        element.css("height", scrollHeight + "px");
      }
      scope.onResize();

      angular.element($window).bind('resize', function() {
        scope.onResize();
      })
    }
  }
})
