No, Intel/AMD makes no difference, x86_64 (EM64T for Intel, amd64 for AMD) vs 
i386 does, but:

Not bbgen itself, as you said you get "Status not available", which is not a 
static html page from bbgen, but usually from bb-hostsvc.sh (calling 
hobbitsvc.cgi).

You may first want to deteremine whether the cgi is timing out speaking to 
hobbitd, or if there is some other problem.

Yes, in my production environment, problems with hobbitd on the RHEL5 x86_64 
box would not result in any noticeable problems, but again, my workstation 
doesn't exhibit this problem (and I usually have about 10 tabs open on 
different hobbit pages, including static and cgi ones, looking at my 
workstation's hobbit install).
