/usr/include/asm/msr.h exists on my linux system (mixed Debian 3.0)
(msr.h came with linux-kernel-headers package, my kernel version 2.4.25)

and compile with WITH_TSC defined worked fine for me about a week ago

PS. just checked my other ancient RedHat 7.2 install and it also has
/usr/include/asm/msr.h
