newbus in revision 1.19. As a result, lnc was, I believe, broken
for all PCI cards. The softc fields `lnc_btag' and `lnc_bhandle'
were not initialised, `rap', `rdp' and `bdp' were initialised to
the wrong values, and the size of the DMA ring memory was calculated
incorrectly.

Paul Richards has further cleanups in the pipeline, but this at
least is enough to make the driver usable with VMware.
