I found the problem with my crapola not working. fatls mmc 1 was listing down my Music folder off my eMMC. What the actual ****? It might be because of damaged fat32 though. Moved bootmenu files to ~/MyDocs/Music/ and it worked. Would probably still be banging rocks together if not for the Gumstix wiki.
mmc init mmc dev 1 fatls 1
