Correct.  With some caveats.  Unless you're clever you have to use all one 
type of module within a single server, they don't mix well.  And the build 
system as it stands will only generate one type at a time.  So if you want 
old module compatibility, you need to say "MakeDllModules NO" in host.def and 
then bludgeon your vendor to give you updated modules.  (Or, someone needs to 
hack imake to build and install both types of modules.)

Note that converting elfloader modules to dlloader modules, in most cases, is 
as easy as:

gcc -shared -o old_drv.so old_drv.o # for single-object modules
gcc -shared -o libolddriver.so --whole-archive libolddriver.a # for ar modules

With occasionally some extra -l flags for things like libgcc on weird 
platforms.
