Well I'm an idiot - the fulltext index on page_text was missing from a default installation. It didn't break searches but probably slowed them down tremendously. Also set engine to MyISAM on page_text to avoid cryptic error messages from MySQL.

#devkit {
	position: absolute;
	top: -385px; right: 0;
	width: 640px; height: 390px;
	border: 1px solid black;
	z-index: 10000;
}

.devkitup {
	top: -385px !important;
}

.devkitdown {
	top: 0 !important;
}
