It doesn't work for me either, but note that the dropcaps style has an absolute size for font-size. That really is not correct if you are going to be changing overall font-size in the document. I changed it to 400% and then it worked just fine on the Kobo. I didn't look into the issue of font-weight but prima facie I don't see where it is set to bold, so that should be easily fixable as well.
