(new to NetBSD)

I am trying to add a Cirrus Logic chipset PnP V34 modem.

The bootrom shows:
Card-01: CIRRUS LOGIC PNP V43 MODEM

on boot:
 com0 at isa0 port 0x3f8-0x3ff irq 4: ns16550a, working fifo
 com1 at isa0 port 0x2f8-0x2ff irq 3: ns16550a, working fifo
 com2 at isa0 port 0x3e8-0x3ef irq 5: ns16550a, working fifo

however:
 isapnp0 at isa0 port 0x279: read port 0x203
 isapnp0: <CIRRUS LOGIC PnP V24 MODEM, CIR3000, , > port 0x2e8/8 irq3 not configured

And when the device is accessed, the system halts.  Suggestions for
fixing this problem would be much appreciated.

Thanks
