Great, thanks for the thoughtful example. I was talking about a prefix from 
the LANANA provider name registry, 
http://lanana.org/lsbreg/providers/index.html, and I'm also aware that many 
potential providers don't have an entry there, yet. Also see 
http://lsbbook.gforge.freestandards.org/lanana.html about LSB's package 
naming recommendations.

The two proposals, next to each other, and even for the same example, seem to 

  Name:      kernel-module-aic7xxx
  Version:   6.2.36


  Name:      adaptec-aic7xxx-6.2.36
  Version:   2.6.13_rc6_1_smp
  Release:   1

Putting aside FUD for a second, where do you see problems querying the rpm 
database, or in Bugzilla? And why do you think the number of source rpms 
would change at all?

You can have multiple packets next to each other, but rpm --freshen (and other 
tools using the same logic) won't work as expected anymore: you will always 
end up with the most recent driver version. Sticking with the same driver 
version by default will break.
