Open source FTW.
2 rows of pictures here, taken with the camera vertically
Used Autopano-SIFT to automatically find the intersection points to allow for the next step
Hugin to put it all together
Emblend to eliminate or drastically reduce visible seams.
I used no-in-camera stitch assist, just a tripod and my mom's A540, though next time I think I'll use my A510, because file size on the A540 was insane...imagine...twenty 6.0 megapixel shots automatically stitched together.
Final product was a TIFF file weighing in at 46mb, I compressed it a bit so you dont have to scroll up and down to view it
I'm gonna do this again tonight downtown.
