Ah, I see (after reading sys/dev/ic/ne2000.c). I'd guess it's a 
AX88190 variant, like the EDIMAX EP4101 which has the same product
ID of 0x1090,

That is, change

    { PCMCIA_VENDOR_INVALID, 0x1090,
      { "PCMCIA", "Fast-Ethernet", NULL, NULL},
      0, -1, { 0x00, 0x40, 0xf4 }, 0},

in your patched if_ne_pcmcia.c to

    { PCMCIA_VENDOR_INVALID, 0x1090,
      { "PCMCIA", "Fast-Ethernet", NULL, NULL},
      0, -1, { 0x00, 0x40, 0xf4 }, NE2000DVF_AX88190},

If that fails, you can guess NE2000DVF_DL10019.
