+Module parameters:
+* type: type of adapter (see i2c-parport or modinfo)
+* base: base I/O address
+ Default is 0x378 which is fairly common for parallel ports, at least on PC.
+* irq: optional IRQ
+ This must be passed if you want SMBus alert support, assuming your adapter
+ actually supports this.
