[ILUG-BOM] HSBC online services not working in Ubuntu/Firefox

I opened an account with HSBC a few days back for my salary deposits. The online@HSBC services are not working in Ubuntu/Firefox. It requires IE 5.0+ or NS Communicator. I tried fiddling with the User Agent string (strangely, most of the IE User Agent strings I found on the net looked like Mozilla/<some stuff>) but to no avail. I've submitted a complaint form but I'm not expecting them to listen to it.

Is there any way other than booting into Windows or using IE from Wine? Other than the fact that I would be using, well, IE or win32, I would lose face in front of my sister whom I berate for carrying out *her* online banking business in win32/IE :-(
