Followup to lxs's answer: I noticed a problem where having both the zoom and --webkit-transform tags at the same time seems to confound Chrome (version 15.0.874.15) by doing a double-zoom sort of effect. I was able to work around the issue by replacing zoom with -ms-zoom (targeted only at IE), leaving Chrome to make use of just the --webkit-transform tag, and that cleared things up.
