Yes, it's -CURRENT. I have same error messages.

Seems to be affected many of Core2Duo CPUs, which are detected by cpuid 
as "Family 6 processor"
For example, my notebook, ASUS F3Jr, give me same error:

CPU: Intel(R) Core(TM)2 CPU         T5300  _at_ 1.73GHz (1731.08-MHz 686-class

For old-core Dual Xeon (Family 10) est is alrady recognised ( I have some of 
them on my workplace)
