Bug#494768: narrowed version range

[cfeller@rocketmail.com]

after further investigation, the sendfile() functionality was 
purportedly working as recently as 7/24, which would put versions at 
2.2.9-5 (apache2.2) and 2.6.25-7 (linux-image).  I verified this by 
looking through apache logs, and there was a datafile (which resides on 
a CIFS partition) downloaded on 7/24.  The apache logs indicate a 
successful GET request (code 200) on 7/24.  Although this doesn't 
confirm a complete download happened on 7/24, it reportely was complete.

Hope that helps...
