I have a wrapper script I use for kernel builds that takes care of that 
(it also supports cross building and building some out-of-tree modules). 
Some snippets from that script below.

BISECTING=
if [ -e .git/BISECT_LOG ]; then
        BISECTING=1
fi
[...]
if [ "$BISECTING" ]; then
        # The version in the next line may need updating before a bisect
        sed -i "s/^SUBLEVEL = .*/SUBLEVEL = 31/" Makefile
        sed -i "s/^EXTRAVERSION =.*/EXTRAVERSION = -bisect/" Makefile
fi
[...]
make ...
[...]
if [ "$BISECTING" ]; then
	# Revert Makefile to avoid errors on 'git bisect good/bad'
        git checkout Makefile
fi

I use the deb-pkg target and also set the .deb package version in the 
second hunk:
KERNELDEBREVISION=$(grep "^git[- ]bisect" .git/BISECT_LOG | wc -l)

This way I end up with a nice series of packages whose numbering matches 
the steps in .git/BISECT_LOG:
linux-image-2.6.31-bisect_1_amd64.deb
linux-image-2.6.31-bisect_2_amd64.deb
linux-image-2.6.31-bisect_3_amd64.deb
...

Hope that help.
