why don't addresses in System.map and /proc/kallsyms match?

i'm a bit curious about something i noticed on my fully-updated F7
system. i was playing with some kernel debugging and noticed that the
kernel-space address for "jiffies" was different between the above two
sources:
$ uname -r
2.6.21-1.3228.fc7
$ grep "D jiffies" /boot/System.map-2.6.21-1.3228.fc7
c130bc00 D jiffies
c130bc00 D jiffies_64
$ grep "D jiffies" /proc/kallsyms
c070bc00 D jiffies
c070bc00 D jiffies_64
shouldn't the addresses be the same? or am i just clueless about
something here?
