Hmm...
steve[/usr/src/sys]$ find . | xargs grep EP_ID_PORT
./i386/boot/netboot/3c509.c: int data, j, io_base, id_port =
EP_ID_PORT;
./i386/boot/netboot/3c509.h:#define EP_ID_PORT 0x100
./i386/isa/if_epreg.h:#define EP_ID_PORT 0x110
./pc98/boot/netboot/3c509.c: int data, j, io_base, id_port =
EP_ID_PORT;
./pc98/boot/netboot/3c509.h:#define EP_ID_PORT 0x100
./pc98/boot/netboot/if_epreg.h:#define EP_ID_PORT 0x100
steve[/usr/src/sys]$ find . | xargs grep ELINK_ID_PORT
./i386/isa/elink.c: outb(ELINK_ID_PORT, ELINK_RESET);
./i386/isa/elink.c: outb(ELINK_ID_PORT, c);
./i386/isa/elink.h:#define ELINK_ID_PORT 0x71d0

./i386/isa/if_ep.c: int data, i, j, id_port = ELINK_ID_PORT;
^^^^^^^^^^^^^
This is why you experienced the problem. This should be
EP_ID_PORT or ELINK_ID_PORT should be changed 0x110. Joerg?
Justin?
./i386/isa/if_ie.c: outb(ELINK_ID_PORT, 0x00);
./i386/isa/if_ie.c: outb(ELINK_ID_PORT, 0xff);
./i386/isa/if_ie.c: outb(ELINK_ID_PORT, 0x00);
./i386/isa/if_ie.c: outb(ELINK_ID_PORT, 0x00);

See above explanation.
