So in general, I would have to build apache before I could use null ciphers?

since there are NULL ciphers I can just use them in apache/mod_ssl by
just changing a setting like:

SSLCipherSuite eNULL

in httpd.conf?

No.  mod_ssl modifiers the ciphers you specify by appending 
':!aNULL:!eNULL:!EXP' in recent versions, or by prepending 
'!aNULL:!eNULL:!EXP:' in older versions.  There were some releases where it was 
possible to specify ciphers as

SSLOpenSSLConfCMD CipherString "eNULL"

and the ciphers you listed were not modified, but that has since been changed.  
If you are not lucky enough to be using a version of apache that is in that 
window, you will need to obtain the apache source, modify mod_ssl, and build a 
custom version.  Be aware of potential license issues with doing this if it is 
for a deliverable.
