(UPDATED) Combo solution:

CSS: /* remove layout selection in create page dialog - 5/17/11 */
 * 1) CreatePageDialogChoose {display:none;}
 * 2) CreatePageDialogChoices {display:none;}

JS: /* remove layout selection in create page dialog - 5/17/11 */ function killLayoutSelection { if (wgPageQuery.match(/(?=%26useFormat)/)) { document.getElementById('wpTextbox1').innerHTML=''; } } addOnloadHook(killLayoutSelection);
