Here it is (from an answer from Andrey to Bjorn, you were not included
yet):

Detected unconfigured Toshiba laptop with ALi ISA bridge SMSC IrDA chip,
pre-configuring device.
Activated ALi 1533 ISA bridge port 0x02e8.
Activated ALi 1533 ISA bridge port 0x02f8.
pnp: Device 00:0a activated.

High: 0x11, Chip 0x0
smsc_ircc_present(), addr 0x0100 - no device found!

Andrey, in addition to Bjorn's patch, could you also apply this one and
try again:
