If I understand your situation correctly, you currently have ingenuitous.com and all sub-domains hosted here at DreamHost, but have the domain registered elsewhere, and you wish to register st0len.net here at DreamHost and transfer all the sub-domains?
If so, then probably the easiest method would be to simply remove the existing ingenuitous.com sub-domains from the hosting system, then rename all the web directories from 'subdomain.ingenuitous.com' to 'subdomain..st0len.net' before adding the new st0len.net sub-domains to the system one-by-one via the panel.
Of-course, you could skip the renaming part and simply specify the correct web-directory when adding the sub-domains.
Edit: I should add that if you wish to do as Nathan suggested and transfer the old domain to DreamHost, the cost of the transfer (and 12 months extension) will be covered by your existing 'domain-credit'.
