I'm trying to use exFAT partition for data exchange between Win7 and OSX. Has native read/write support in OSX and supports big files. I like to hide data partitions from Chameleon boot by using labels. This patch adds exFAT volume label support. exFAT shares partition type with NTFS (0x7) and easiest way of adding it was through ntfs.c module.
Works for me, needs testing.
