DONE!!!
First download Text Edit from the market.
Use it to open the file /sdcard/debian/bootdeb.
Look for the line that says, busybox insmod ext2
Edit it to read busybox modprobe ext2 (be sure to save!)
Launch it.
This edit will silently use the modprobe that I mentioned earlier.
I have another idea. Give me another 10 minutes.
EDIT:
Idea was to place a script that would trigger the bootdeb script in the / directory. The system won't let me. Oh well.
I still want to make the debian files visible to android, but I'll try again another day.
