Nevermind, figured it out. The problem was i had only set 2 TDM Slots in my board file in the kernel (arch/arm/mach-omap2/board-am335xevm.c). This was the culprit:

I also changed this in sound/soc/davinci/davinci-mcasp.c (although i don't know if it has any bearing on the actual channel limit of mcasp0 or not):

I swear half the time i post something i figure it out right after... doh!
