MSR_IA32_CORE_CAPABILITY (0xcf) contains bits that enumerate some model specific features. The MSR 0xcf itself is enumerated by CPUID.(EAX=0x7,ECX=0):EDX[30]. When this CPUID bit is 1, the MSR 0xcf exists. Detailed information on the CPUID bit and the MSR can be found in the latest Intel 64 and IA-32 Architectures Software Developer's Manual.
