Undocumented MSRs

I found software that used

[bash]MSR_CORE_THREAD_COUNT
MSR_PMG_CST_CONFIG_CONTROL
[/bash]

and also in binary file I see addresses 0x35, 0xce, 0xfc, 0xaa, 0x1ac, 0x1ad.

I think they a model specific but why there is no decription in any Intel documentation including 253668.pdf and 253669.pdf?

Is Intel going to publish more information about MSR registers?
