Yes.

Tried it. Not working:
sio1 at port 0x2f8-0x2ff irq 3 on isa0
sio1: type 16550A
[...no sio2...]

Weird. What IRQ would the probe use then??? It is more likely to be the
opposite. The modem being on irq 10 and the probe trying irq 5... I will
try to setup a kernel with sio on irq 10. (?)

Strange.. I think there's a problem with the PnP probe since unrecognized
PnP devices are supposed to be identified and reported as such, along with
their PnP ID...
