I tried this on my Toshiba Satellite 1800-314 and the device gets IO resources but is still disabled. echo activate > ... will enable it but the smc-ircc2 driver still finds that the device is disabled (in 2.6.10-rc2+yesterdays BK):

Looks like there is also a enable/disable bit in the actual LPC device, or maybe it needs also a fir address and/or irq?
