I was going to say, I have both gitweb and smart http support running in
parallel, it's not terribly complicated.  The way I'm doing it is a bit
older (mainly that long ScriptAliasMatch broken out more), but it's
still only 11 lines to the apache config:

# Various environment setup, should be obvious
SetEnv GIT_PROJECT_ROOT /path
SetEnv GIT_HTTP_EXPORT_ALL 1
SetEnv GIT_EXEC_PATH /usr/libexec/git-core/

# Here so that we can do straight wget fetches for the objects files,
# pack files and refs heads.
# This isn't strictly neccisary, but if it's done we can use the inbuilt
# sendfile() of apache for the sending of those files vs. funneling them
# through the CGI
AliasMatch ^/(.*/objects/[0-9a-f]{2}/[0-9a-f]{38})$		/path/$1
AliasMatch ^/(.*/objects/pack/pack-[0-9a-f]{40}.(pack|idx))$	/path/$1
AliasMatch ^/(.*/refs/heads/.*)$				/path/$1

# Meat of how to make this all work
ScriptAliasMatch "^/(.*/HEAD)$"
/usr/libexec/git-core/git-http-backend/path/$1
ScriptAliasMatch "^/(.*/info/refs)$"
/usr/libexec/git-core/git-http-backend/path/$1
ScriptAliasMatch "^/(.*/objects/info/[^/]+)$"
/usr/libexec/git-core/git-http-backend/path/$1
ScriptAliasMatch "^/pub/scm/(.*/git-upload-pack)$"
/usr/libexec/git-core/git-http-backend/path/$1
ScriptAliasMatch "^/pub/scm/(.*/git-receive-pack)$"
/usr/libexec/git-core/git-http-backend/path/$1

Just an example anyway, the paths have been shortened to fit e-mail better.
