Good to hear but something is still wrong on my laptop as nothing worked 
as expected :(

Since I have a working custom kernel including the fix from my original 
patch it was clear from boot that the last patched kernel did not touch 
the MSR we want to modify at all. The machine was slower compared with 
my kernel using the original patch. As I use the show_msr option, a 
quick look at the dmesg proved that easily. Nowadays that processors 
have many cores, I wonder if the kernel should report which CPU MSRs are 
displayed at dmesg.

Take your time to see what is wrong, we already have one working kernel 
for our machine :)
