New Post: BUGNet theming: left sideMenu

I've been theming BUGNet, but I've run into a small problem. The left hand sidemenu which is present on the Project Administration and Application Configuration pages has its background set inline, rather than in CSS, and thus cannot be changed.

Is there any way to work around this?

The code as it appears in a browser is:
<div id="menu"><ul class="sideMenu"><li id="ctl00_ctl00_MainContent_Content_AdminMenu_ctl00_ListItem" style="background: #C4EFA1 url(../../images/page_white_gear.png) no-repeat 5px 4px;" class="on"> ...</li> ...</ul></div>
