all OK (huge read of binary/sets etc.) until suddenly (hmm seems to be
reproducible with cvs - rather odd):

  rtk0: transmit underrun; new threshold: 320 bytes

Then no more connection. Pulling the card out, popping it back in and
giving it an ip number makes it work again..

I remember cbb0 not being defined

  cbb0: NOT USED because of unconfigured interrupt

until I removed acpi, and added PCBIOS to this i386 kernel, then the
device/vendor/prod/pin/.../ table doesn't appear and

  cbb0: interrupting at irq 11

Maybe these 2 observations are related?
