Ok, spent the entire evening yesterday reinstalling Cacko with the new patch plus all the rest of my software and user settings (urgh..).
Had a bit of a scare when I couldn't get the C-Guys SDIO drivers to work on Cacko, but it turned out my Windows PC had corrupted the sdiomgr script.
So now everything's working flawlessly, plus I gained 30 MB of free internal storage
Thanks again Maslovsky.
(Now I need to find some time to update my conversion guide)
