Hi Knottyboy, and welcome to AF
Simple2Ext is only for CyanogenMod, so you can forget that one.
There are quite a number of apps2sd scripts out there, not just the one from the CM threads at XDA. But Evervolv Turba is Nikez ROM, right? That already includes an apps2sd script (/system/etc/init.d/10apps2sd), which I think should work automatically. I don't think it will use the same terminal commands as the DarkTremor script, which the CM one is based on, so don't worry if commands like "a2sd install" don't do anything because that's only some scripts do that.
Does Titanium show the partition being used, or completely empty? These scripts move stuff to the ext partition, but the phone doesn't report having extra storage. So the phone will still say it has 147 MB internal space in total (stock hboot), only you'll be using a lot less of it than you would expect (because stuff is on sd-ext instead). So if the partition is being used that means the a2sd is working correctly.
If you want to check in more detail, try a root enabled file explorer (ES File Explorer, Root Explorer) and just look what's on sd-ext. Or there's a little app called DiskUsage in the Play Store that can show you this (select the root only options, then show sd-ext).
Ah, I see you worked it out in the meanwhile. Is that using the built-in script, or one you installed yourself? I ask because I didn't spot anything in the ROM's script that would parse those commands.
