You can set a custom property of the password field upon focus, and bypass
the username focus if that property flag is set.  Here's a skeleton to work
from (watch for email word wrapping in the onload handler):

<body onload="if (!document.forms[0].pw.typing)
document.forms[0].un.focus()">
<form>
Username:<input type="text" name="un" /><br />
Password:<input type="text" name="pw" onfocus="this.typing=true" />
</form>
</body>

So, it's using onfocus, but not taking up global var space. Works in quick
tests of IE6 and Mozilla.
