Interestingly enough, I had a coworker download IE8, and he checked
OpenStreetMap and had limited problems. There are clearly some pretty
major defects in their rendering engine -- the most visible one I saw
was the lack of clipping based on a div having "overflow: none" which
affected every map except for Virtual Earth (Microsoft's map offering), 
but at least some portion of the OpenLayers code worked fine.

The same was true of the other layers that are presented within
http://openlayers.org/dev/examples/spherical-mercator.html , which I
couldn't get to screw up at all.

I think that IE8 will clearly undergo some pretty significant
development before being released, to the extent that I'm not even
worrying about it yet: there were too many blatantly obvious rendering
issues to even be concerned with what particular aspects of the
rendering were broken.
