I am building an openstreetmap with some geometry points, using this example, and using the

map = new OpenLayers.Map({
    div: "mapdiv",
    theme: null,
    projection: new OpenLayers.Projection("EPSG:900913"),
    displayProjection: new OpenLayers.Projection("EPSG:4326"),
    maxExtent: new OpenLayers.Bounds(-20037508.34,-20037508.34,20037508.34,20037508.34),
    maxResolution: 156543.0399,
    numZoomLevels: 19,
    units: 'm',
    controls: [
         new OpenLayers.Control.Attribution(),
         new OpenLayers.Control.TouchNavigation({
                dragPanOptions: {
                    enableKinetic: true
         new OpenLayers.Control.Zoom()

map.addLayer(new OpenLayers.Layer.OSM());
var style = OpenLayers.Util.extend({},['default']);
style.graphicWidth = 30;
style.graphicHeight = 32;

style.externalGraphic = "img/point.png";

var mapmarkers = new OpenLayers.Layer.Vector( "Markers");

var features = [];
var points = [];

for (var i = markers.length - 1; i >= 0; i--) {
    points[i] = new OpenLayers.Geometry.Point( markers[i].latlng[0], markers[i].latlng[1] );
    features[i] = new OpenLayers.Feature.Vector( points[i], null, style);
map.setCenter(new OpenLayers.LonLat(points[0].x, points[0].y), 5);

I'm getting the correct number of points on the map, but they are sitting at a lat/lang of 0,0. The only difference between the features variable I'm sending to addFeatures .. features.geometry is that it has a bounds object with top/bottom/right/left equivalent to the x and y that isn't present in the example..

If I use the example's map.addLayer(new OpenLayers.Layer.WMS( "OpenLayers WMS", "", {layers: 'basic'} )); both points get placed but they are in Antarctica instead of Quebec (at least in different places then)

You will have better chances of getting an answer if you rephrase this as an actual question.

The problem is with different map projections. Probably you'll have to project your latLon points (which are in WGS84 / EPSG:4326) to Web Mercartor (EPSG:900913) by using something like the projection example from OpenLayers.
