Family 0xF, extended family 1, model 2.

Or, to quote a certain driver that happend to be posted on this list
recently:

static bool __devinit has_erratum_319(void)
{
	/*
	 * Erratum 319: The thermal sensor of older Family 10h processors
	 *              (B steppings) may be unreliable.
	 */
	return boot_cpu_data.x86 = 0x10 && boot_cpu_data.x86_model <= 2;
}
