Enable the driver in sys/conf/files.i386. In isa/isavar.h increase ISA_NPORT from 32 to 50. This is required because this brain-damaged card maps 49 (!) port ranges. This does not have a negative impact because this value only specifies the maximum number of entries in a linked list and not the size of an array which is allocated in all drivers. The register/fifo access routines were not newbus-ified because 1) I knew that the old code worked and is simpler and more efficient 2) the if_ed driver does something similar and 3) the newbus macros collapse to inb/outb anyway.
