That's going to be interesting, as all distros pretty much use the same
kernel, it will just depend on who is "newer" at the moment, right?

Most distros don't build drivers into the kernel, so you should be fine
with what you have today, right?  Or have you run into problems with
this?

Why not just use the baseline kernel as a model for this.  Do a 'make
allmodconfig' and then extract the data and publish it that way.  No
kernel changes are needed, and then any distro can be easily matched up
by this based on what they are using.  That will save you time in
downloading zillions of distro releases, and provide a nice easy way to
show what the kernel.org releases support.

thanks,
