The KA640 uses the exact same bizarre setup for the LANCE as the DS3100
does.  So if you can get DS3100 LANCE support from pmax port, it should
work on the KA640.

The setup is as follows: there's 128KB of address space in which 64KB
of shared RAM lives (which is accessable by the LANCE).  The host this
memory as 32K longwords of which only the low word contains data.  The
LANCE just sees 32K words of data.
