I not it doesn't help but I use this css quite a lot, a simple and validated way to get rounded: (All browsers) Good for a basic rounded surround...No images at all..

b.rtop, b.rbottom{display:block;background: #D4CCAA} /* controls corner colour */
b.rtop b, b.rbottom b{display:block;height: 1px;
overflow: hidden; background: #FFF}/* controls background colour */
b.r1{margin: 0 5px}
b.r2{margin: 0 3px}
b.r3{margin: 0 2px}
b.rtop b.r4, b.rbottom b.r4{margin: 0 1px;height: 2px}
