There is a pronounced performance increase on some phones... not so much on these ones. Though maybe the 500 is more ripe for performance increase than the 800, so it might be worth a shot.

system goes on ext2 partition #1, data goes on ext2 partition #2. Open up /init in the rootfs; near the beginning, there's a whole section that tests if mmcblk0p2 and p3 exist, and if so, sets a PARTITIONED flag and goes through a bunch of steps. It looks to make sure there's an installedsystem.sqsh, and, if there is, tries to boot off the ext2 partition.

What you want to do is boot into android (using the standard method), mount mmcblk0p2 in a temporary directory, manually 'cp -a' everything from /system to /mnt/temp (or whatever), optionally do the same for mmcblk0p3 and /data, then reboot to WinMo, and move the files around so that it chooses to boot from partition instead of file.

I might be forgetting some steps or some pitfalls, as it's been quite a while since I've done any of that.
