Sure, boot a recent linux kernel (2.0.34 or later I believe) or
any 2.2 kernel, and then do:

1 root@red:/# cat proc/cpuinfo
processor : 0
cpu : 586
model : AMD-K6tm w/ multimedia extensions
vendor_id : AuthenticAMD
stepping : C
fdiv_bug : no
hlt_bug : no
f00f_bug : no
fpu : yes
fpu_exception : yes
cpuid : yes
wp : yes
flags : fpu vme de pse tsc msr mce cx8 10 mmx
bogomips : 399.77

As you can see, no f00f here.
