That is the only way.  Joys of rolling release.

What has pushing a new version of virtualbox got to do with rebuilding
modules when the kernel is updated?  Rebuilding modules on kernel update is:

for pkg in <module package list>; do
   archco <pkg>
   // awk/sed line to bump pkgrel
   testing-x86_64-build && testing-i686-build
   testingpkg "module rebuild"
done

OK - I was wrong.  That is six lines (or seven if you count the line
with && as two lines...).
