Maybe you've already checked this but... The Ethernet Howto says that
this card must be "set" (jumper, software config???) to Ultra 
compatibility mode in order to work with the Ultra kernel driver.
Here's the excerpt:

  5.35.4.  SMC EtherEZ (8416)

  Status -- Supported

  This card uses SMC's 83c795 chip and supports the Plug 'n Play
  specification. It also has an SMC Ultra compatible mode, which allows
  it to be used with the Linux Ultra driver.  Be sure to set your card
  for this compatibility mode.  See the above information for notes on
  the Ultra driver.

  For v1.2 kernels, the card had to be configured for shared memory
  operation. However v2.0 kernels can use the card in shared memory or
  programmed i/o mode. Shared memory mode will be slightly faster, and
  use considerably less CPU resources as well.

  Note that the EtherEZ specific checks were added to the SMC Ultra
  driver in 1.1.84, and hence earlier kernel versions will not detect or
  handle these cards correctly.
