The 82586 gets the root of its configuration data structure from a fixed
location in memory (the last few bytes).  This location changes with the
amount of installed memory on cards which allow it, and complicates driver
writing.  A simple workaround is to change all references to the location
at the end of the 16K to a new location the same distance below the end of
the 8K.  Then, re-size the number of receive buffers and you're on your way.

PC/TCP's drivers for the NI5210 do this...
