Do you think that I have drunk such kool-aid?  I was a Debian developer for 
many years before joining Red Hat.

They designed it badly.  Keeping interfaces synchronised isn't that difficult, 
all the code that gets into the main-line kernel keeps the interfaces the 
same for long periods of time.  Interface changes have version numbers and 
applications can (if necessary) support both interfaces.

If they are producing multiple packages for each distribution then they must 
have the builds automated.  It should be quite easy to make an automatic 
build script that builds RPMs, Debian packages, and any other types of 
package that seem necessary.

If the interface between kernel and user-space doesn't change then all they 
need to do is have one RPM for the shared objects and a set of RPMs that 
install .ko's in the correct places for each kernel.  You would just have to 
make sure that every time you upgrade your kernel you install the matching 
drivers.  If you didn't install the drivers then the symptom would be a lack 
of 3D graphics which would be easy to fix.
