kernel-config: disable SUNDANCE_MMIO in next build. For the reason see 
bugreport by Alexander 'Leo' Bergolth:

##########################################################################
The grml-kernels define CONFIG_SUNDANCE_MMIO, which breaks detection of
several network cards, e.g. the Dlink 580-TX 4-port network adapter:

-------------------- 8< --------------------
config SUNDANCE_MMIO
        bool "Use MMIO instead of PIO"
        depends on SUNDANCE
        help
          Enable memory-mapped I/O for interaction with Sundance NIC
registers.
          Do NOT enable this by default, PIO (enabled when MMIO is disabled)
          is known to solve bugs on certain chips.

          If unsure, say N.
-------------------- 8< --------------------

As the Documentation states, NOT defining CONFIG_SUNDANCE_MMIO would
make several cards work (most notably my Dlink-card ;)).
