+x86_64 and i386 return 0 when reading MSR_TSC
+
+Running NetBSD 6.1 (i386 and amd64) under QEMU (from git - 1.5.50 is the version it shows) results in an incorrectly set
+TSC frequency (set to 0), because NetBSD uses rdmsr(TSC_MSR) for its serializing CPU counter.
+
+To reproduce the problem, you can run an install ISO of NetBSD 6.1 (either i386 or amd64, depending on which qemu).  Quit out of the installer, and you're left at a root prompt:
+
+# sysctl machdep.tsc_freq
+machdep.tsc_freq = 0
+
+...on real hardware, it will return the TSC frequency:
+
+# sysctl machdep.tsc_freq
+machdep.tsc_freq = 3292685070
+
+...this causes problems with a number of applications.
+
+The NetBSD code which reads the MSR is here:
+
+http://nxr.netbsd.org/xref/src/sys/arch/x86/x86/tsc.c#262
+
+... the "rdmsr(MSR_TSC)" call in cpu_counter_serializing() always returns 0 when run under QEMU.
