Well, according to opcode.lst on http://www.chat.ru/~phg
I get:
"Note: Some Last NexGen Nx586 support CPUID instruction, but never
support ID flag in EFALGS, so check it with #UD hook."

On my particular processor, I get:
processor : 0
vendor_id : NexGenDriven
cpu family : 5
model : 15
model name : 04/0f
stepping : 15
fdiv_bug : no
hlt_bug : no
sep_bug : no
f00f_bug : no
coma_bug : no
fpu : no
fpu_exception : no
cpuid level : 1
wp : no
flags :
bogomips : 67.17
.... but the way I got this was to modify head.S to do something
else. NexGen's get caught on the 386 detection and will therefor be
detected as a 386 unless something else is done. I modified a line in
head.S (basically broke it for a test). Made the "je is386" stand as it
was, but moved the "is386:" label up to the cpuid routine. After that I
got the output above. Something is clearly wrong with the model name :)
