On the feature plan comparison page, you say that SSH access to your account is not normally turned on, but could be turned on by request. Is all I have to do to write support an e-mail about it to get it turned on? I currently have my own linux-machine and am quite used to using the shell prompt, and would not like to miss it if I moved to your hosting. (I am on ADSL, so your site would provide better bandwidth).

Yes, you should write.
