Well, after doing copious backups, formats and restores of my SD cards, I've got an answer for this... Froyo's equivalent of apps2sd does *not* require that you create an EXT formatted partition on your SD card. Virgin Froyo does not provide any way to create an EXT partitions, and it stores applications on your SD card without you having to do that. Where it stores applications on the SD card I'm not sure yet. Based on that, I'm also guessing that if you've got apps2sd with an EXT partition already running on your Drioid, installing virgin Froyo probably *will not* provide native support for any applications that are stored on your existing EXT partition. That is just a guess, I've never run a ROM that provided apps2sd functionality, but it seems pretty logical, although I'll bow to anyone's experience based wisdom on this. Comparing Froyo with apps2sd, of my 90 odd installed apps, about 8 are currently supporting Froyo's spec for moving to SD, and therefore right now we probably aren't going to save a lot of space with this functionality. Maybe later on it will be more helpful. It's also important to note that active widgets, live wallpaper, skins and any other applications that need to be dynamically available to the system at boot time probably should not be moved to SD card. If they are, they may not be fully functional for you after yoru Droid finishes booting (for example, SetCPU's widget gets messed up this way).
