Feedback of /sbin/vboxconfig on failing module load not always helpful

Failing of /sbin/vboxconfig due to failing module load results in the feedback

$ sudo /sbin/vboxconfig Stopping VirtualBox services. Starting VirtualBox services. Building VirtualBox kernel modules. failed: modprobe vboxdrv failed. Please use 'dmesg' to find out why.

There were problems setting up VirtualBox.  To re-start the set-up process, run
as root.

However, dmesg doesn't reliably show the reason for the failure, in my case it contains no new message in comparison to dmesg executed right before running /sbin/vboxconfig whereas sudo modprobe -vvv vbox* shows the reason for the failure:

Please note that I'm requesting a fix for the feedback of the script, not the issue shown in the output of modprobe.
