We just went through exactly that and Feedburner came out with its “Official” instructions on 7/11/07 (Right after we got it going) and here they are. It was quite simple actually (one click and a copy/paste) and well worth it! We added a bunch more subscribers to our feeds. We sure do love them statisticly goodnesses. And yes we do make up words regularly :)

FeedBurner Integration for Blogspot Blogs
Hot on the heels of last week’s
much-ballyhooed free
FeedBurner for everyone
, we are very excited to announce the immediate
availability of one-click redirection for Blogger Blogspot blogs (note our fine
use of both alliteration and first syllable congruence).
If you host your
content on a Blogger blog with a blogspot.com address (or use Blogger’s “custom domain
feature), you can now redirect your native Blogger feed to your FeedBurner feed
(quite easily, might we add). Gone are the muggy, languorous days of wrestling
with “autodiscovery” tags in foreboding corners of your Blogger template code or
hacking through this tangled discussion
thread
for a glimpse of configuration clarity. Starting right now, you just
log into your Blogger account, select Settings Site Feed, enter your
FeedBurner feed address and click “Save Settings.” Zap! Pow! Kraaakkkk! Now
you’ve got the complete picture of how your content is being consumed out here,
out there, out everywhere.
Why is redirecting so important? We’re glad you
asked. By redirecting your feed, you can get a true picture of how many
subscribers you have. Some of you might even see a few more subscribers
magically appear, though results will most certainly vary. Why so? Sometimes,
publishers inadvertently fragment their feed audience by offering more than one
feed address on the blog itself or within their autodiscovery tags (the method
by which feed readers automatically detect the address of your feed for
syndication purposes). This results in some subscribers not being counted, and
no one wants that in a world where everyone should count for something. By
redirecting your feed, you can consolidate any straggler subscribers and greatly
improve your ability to effectively measure your audience.
Getting startedOur Blogger
QuickStart guide has been updated to include all the necessary info for
redirecting your feed. And, since you’ve made it this far in today’s post, now
is a good time to let you know we’re still accepting Publisher Buzz submissions, so if
you have a good story to tell about your newly integrated Blogger feed or your
experience using our feed-related services, submit it to
buzz@feedburner.com.

Blog on, good peoples.
