If you wanna play with LInux/s390, you can get a login to your very
own linux VM for free over at:
http://www-03.ibm.com/servers/enable/site/testdrive/zseries/index.html

I've ported/validated some different open source packages on
Linux/s390 for the sheer hell of it before, it's pretty much like any
other linux.  I have no idea if they have any VM/CMS sessions
available for use by developers (for love or money).  They charge
(gasp!) $2000+/MONTH for use of a z/OS virtual system (MVS by a new
name).
