The following should speak for itself:

Looks like I've got a working kernel 2.4.22 patch for the Home edition so far. I'll give it a couple more test runs, then see if it works on the Pro edition. It's quite a complex patch system and if things go wrong half way through, it could get messy, I'll try and neaten it up a bit before release ;)
