I've installed Swiftweasel into Intrepid using the Hoary deb file from sourceforge, and I have compared Firefox 3.0.5 with Swiftweasel 3.0.3 side-by-side. I haven't noticed any difference wrt zooming.
I can also confirm, that uninstalling font packages helps with the zooming performance. There are still a lot of fonts, though. Not knowing what these are for, I'd rather wait for this bug to resolve.
