No. The kernel from Sid has support for MSR as module:

root@host:~# modinfo msr
filename: /lib/modules/4.14.0-3-amd64/kernel/arch/x86/kernel/msr.ko
license:        GPL
description:    x86 generic MSR driver
author:         H. Peter Anvin <hpa@zytor.com>
depends:        
intree:         Y
name:           msr
vermagic:       4.14.0-3-amd64 SMP mod_unload modversions 

Did you run the script as user or as root?

I get the same errors as you if I don't run the script as root. For the
checks to be reliable, *including* the dmesg-check, you need to run the
script as root.

Grüße,
Sven.
