Yes, it's totally broken. Here's a stupid comparison script I hacked up,
maybe it's useful for someone:

#!/bin/bash
#
# gitstat-cmp.sh
#
# Sample gitstat input:
#   1 Adrian Bunk                45
#   2 Ralf Baechle               42
#   3 Alan Cox                   25
#   4 David S. Miller            24
#   5 Jeff Garzik                24
#   6 Al Viro                    19
#   7 Pavel Emelyanov            19
#   8 Tejun Heo                  18
#   9 Paul Mundt                 17
#
# Sample gitstat-cmp.sh output:
#
# Bogus entry for "Adrian Bunk" (gitstat 45 kernel 137)
# Bogus entry for "Ralf Baechle" (gitstat 42 kernel 143)
# Bogus entry for "Alan Cox" (gitstat 25 kernel 70)
# ...
#

# Example usage: sh ./gitstat-cmp.sh gitstat.txt . v2.6.23 v2.6.24-rc2
[ "$#" -ne "4" ] && \
	echo "Usage: $0 <gitstat list> <kernel tree> <tag1> <tag2>" && exit 1

IFS="
"
pushd $2 > /dev/null || exit 1

for line in $(sed -e 's/^[ \t]*[0-9]* //' < $1); do
	name=$(echo $line | sed -e 's/  .*$//;s/\t.*//')
	count=$(echo $line | sed -e "s/$name//g;s/^[ \t]*//;s/[ \t]*$//")

	for srcline in $(git shortlog $3..$4 | grep "^$name"); do
		srccount=$(echo $srcline | sed -e 's/.*(\(.*\)):.*$/\1/g')
		if [ "$count" -ne "$srccount" ]; then
			echo "Bogus entry for \"$name\" (gitstat $count kernel $srccount)"
		fi
	done
done
