I have a similar situation in that I have an internal on one of my
machines. I set the IRQ on the _modem_ to IRQ 5 and left the kernel config
alone. works fine with cuaa2 for dial-out and ttyd2 for dial-in. 

You now have two uarts responding to the interrupt request and confusing
the kernel. Try the -c option at the boot prompt and disable sio1 -- it
may work. Better, though, to reconfig the kernel to IRQ 5 and set your
modem to respond to IRQ 5.
