It may even be simpler if you remember that mmcblk0p1 is actually the 3rd 
partition in physical order:
# fdisk -l /dev/mmcblk0

Disk /dev/mmcblk0: 1977 MB, 1977614336 bytes
4 heads, 16 sectors/track, 60352 cylinders
Units = cylinders of 64 * 512 = 32768 bytes

        Device Boot      Start         End      Blocks  Id System
/dev/mmcblk0p1           57376       60352       95264  83 Linux
/dev/mmcblk0p2           42727       57375      468768  83 Linux
/dev/mmcblk0p3               1       42726     1367224  83 Linux

74a7:8000 = 1.957.134.336.
The start of mmcblk0p1 is at 57376 * 64 * 512 = 1.880.096.768.
So there's still a gap to explain.
