I was pretty sure (without citations) the quark is a die shrunk pre-mmx pentium (but post division table bug), are you sure it's a 486?

The right era pentium had the same LOCK prefix issue (we used to call it the F00F bug)

Edit: Thanks for link; I must have anchored on the instruction set and ignored that it was using the 486 pipeline.

"The new x86 CPU uses an old-school 486 scalar pipeline and the original Pentium instruction set with some modern enhancements"

The fact it's got the f00f bug certainly made it sound like a dusted off pentium core.
