Here's the fix we use. It leaves the timer on the left, but ensures that there is space for it next to the questions.

In your theme's stylesheet (moodle/theme/yourtheme/styles_layout.css), add the following:

/* allow a fixed space for the timer so it won't cover question text */
.que .content {
float: none;
margin-left: 155px;
width: auto;
}

/* adjust the timer width for IE */
#timer .generalbox {
padding: 0;
}
