Roland,
not really an answer to your question, but note that - with a recent
gdal - you can also create kmz by using the kmlsuperoverlay output
format, e.g.:
gdal_translate -of kmlsuperoverlay <infile> out.kmz
your infile need be a rgb or rgba format (if you want to maintain
transparency, add '-co format=png' to the gdal_translate command,
otherwise jpeg's will be created for the tiles).
Regards,
Vincent.

Thanks Brian,
I have reviewed OSGeo4W\bin\gdal2tiles.py and specifically line 1597
containing the href tag to the png file:
<Icon>
<href>%(ty)d.%(tileformat)s</href>
</Icon>
I was curious if someone had any idea on how to modify this href tag to
include the relative path as Brian suggests below. I see that the
appropriate path is already included in the name tag if the .kml is
changed to .png. Any ideas on the best approach would be appreciated.
Also, is this relative path something that should be added to the
general release to support kmz compression?
Thanks,
Roland

the problem is in /12/1211/2558.kml line 26
<href>2558.png</href>
this should be a relative path from the root of the zipfile not from
2558.kml
