I only have 1.3.6 installed, so don't have the HTML support, but you want 
to use the .tail of the b elements I think.  With the XML API:

from lxml.etree import fromstring
doc = fromstring('<doc>text1<b>text2</b>text3<b>text4</b>text5</doc>')
b1, b2 = doc.getchildren()
print doc.text + b1.tail + b2.tail

print doc.text+''.join(c.tail for c in doc.getchildren())
