That's quite interesting, as I'm currently running on a Cyrix DX4-100
(with improper motherboard jumper settings as written in my motherboard's
manual that make it effectively a DX3-75, it's actually supposed to be a
DX3-99.9, this will change soon).  Yet on startup NetBSD gives me the
following message:

CPU: Cx486DLC (Cyrix 486-class CPU)
WARNING: CYRIX 486DLC CACHE UNCHANGED.

Why does NetBSD think I've got a 486DLC?

Any thoughts?
