You can refer to the thread:
http://n2.nabble.com/-1666---One-Single,-Mother-Of-All-Vector-Layers-td1340452.html

I am the one who is using this patch. IE actually has more problem than I
posted previously:
1. the evt.target is not work in IE, IE support evt.srcElement only
solution: you can make use of prototype.js event model to simplify your code
(Wrapped by OpenLayer.Event)
beware the IE support DOM Level 2 event poorly.
2. if you add the feature once, IE work ok; but if you get the feature from
a rendered layer, the mother layer cannot hold the correct position when you
move the map or zoom. 
The solution I found is tricky: detach the sub-tree of the lowest group of
each rendered layer (root is group) to the mother layer*. Features needed be
kept in their source layer, and every feature VML element need to have a
additional groupName other than the featureId to tell the event handler
where to go to find the feature for event processing. (groupName->source
Layer (slayer)->feature = slayer.getFeaturebyId(featureId))
* the tree detaching is for VML engine only, SVG will have problems about
this. (Canvas is unkown, but it should similar to SVG)
3. After fixing the position, the z-order come to be a problem: the layer
disappear after certain zoom-ins. 
***No solution***

Hope it help
