hi there - you couldn't detail how you do this by any chance? I came upon this thread whilst searching for active x. As my employers web portal with its link to my remote desktop uses an active x component I can't access it on my N900. Its an issue as my work is always out of office and frequently by road side/on hill/or similar area wih lack of ie enabled comps. Whilst I rarely feel the need to check my rather unimportant email there are a lot of policy documents etc that can be useful to access.
I understand that many people will say get the it dept to review its reliance on ms products the reality is this won't happen unless the chief exec wills it!
