The Kernel itself contains a pretty good explanation.
From /usr/src/linux/Documentation/Configure.help:
| I2O support
| CONFIG_I2O
| The Intelligent Input/Output (I2O) architecture allows hardware
| drivers to be split into two parts: an operating system specific
| module called the OSM and an hardware specific module called the
| HDM. The OSM can talk to a whole range of HDM's, and ideally the
| HDM's are not OS dependent. This allows for the same HDM driver to
| be used under different operating systems if the relevant OSM is in
| place. In order for this to work, you need to have an I2O interface
| adapter card in your computer. This card contains a special I/O
| processor (IOP), thus allowing high speeds since the CPU does not
| have to deal with I/O.
Cheers,
