HTC Hero : Where Are Apps Stored After "move Apps To SD"

I have a rooted HTC Hero, and I was, until a couple of days ago, running MoDaCos 1.6 ROM.

I decided, (foolishly perhaps?) to try to move my apps to the SD card. I partitioned the Sdcard using Amon Ra's boot recovery screen and all went fine. I then used the option "move apps to SD" also included in the boot recovery. I am now using Froyd Villain's newest froyo ROM, and all the apps are working fine but the apps aren't on the phone, and they aren't on the ext- partition of my sdcard, so i come to the conclution that they must be on the fat 32 partition, but how the heck do i access them? Neither the phone nor my computer can access the fat32 pertition of my sdcard.

The problem being that I've just bought a larger sdcard, and I want to transfer all my apps to that card, but I can't since I can't even locate the files.
I have tried backing up all the aplications using titanium backup, but the phone won't boot without the sdcard, so i cant import them onto the new card. Any suggestions?
