Something like that also happened with my UMC 486. It's now detected as:
Linux version 2.6.8.1-router (root@pentium) (gcc version 3.3.4) #1 Thu
Sep 9 12:42:25 CEST 2004
...
CPU: After generic identify, caps: 00000000 00000000 00000000 00000000
CPU: After all inits, caps: 00000000 00000000 00000000 00000000
CPU: UMC UMC UMC ff/02 stepping 03
It used to be detected more nicely in 2.4.x (I don't remember exact string).
