Is v2.1.x CPU bug detection accurate?

Running kernel v2.1.117 on a RedHat 5.1 system, a display of /proc/cpuinfo shows
me this:

processor : 0
cpu family : 5
model : Pentium 60/66
vendor_id : GenuineIntel
stepping : 7
fdiv_bug : no
hlt_bug : no
sep_bug : no
f00f_bug : yes
fpu : yes
fpu_exception : yes
cpuid level : 1
wp : yes
flags : fpu vme de pse tsc msr mce cx8
bogomips : 23.96

Note all the bugs I supposedly do *not* have. As shown above, my processor is a
Pentium/60. This ancient Gateway box was one of the first Pentium machines on
the market. This being the case, is it really possible that I don't have the
fdiv bug? (This is the bug that caused a very public uproar 7 years ago.) I
would think that this early version of the Pentium, even if it is stepping #7,
would have most of the bugs found in the Pentium architecture.

FYI, when building the kernel, I opted for the backward-compatible procfs
support. Also, my installed version of procps is v1.2.7. According to
Documentation/Changes this version should be okay with 2.1.117.

Is my CPU really this bug-free?

Thanks.
