17 integration such as an on-chip I2C controller.
30 - Dual serial ports
31 - PCI interface
32 - Flash access (MTD/JFFS)
33 - I2C through GPIO on IXP42x
34 - GPIO for input/output/interrupts
35   See arch/arm/mach-ixp4xx/include/mach/platform.h for access functions.
36 - Timers (watchdog, OS)
41 - USB device interface
42 - Network interfaces (HSS, Utopia, NPEs, etc)
43 - Network offload functionality

83    problematic if using video cards and other memory-heavy devices.
99 Currently the code only handles level-sensitive GPIO interrupts
108    interface, one to 4-port 10/100 switch, and the third to and ADSL
111    the platform has two mini-PCI slots used for 802.11[bga] cards.
118    replaced with mini-PCI slots and a CF IDE interface hanging off
137    added. One issue with this board is that the mini-PCI slots only
138    have the 3.3v line connected, so you can't use a PCI to mini-PCI
154 - Add support for Coyote IDE
155 - Add support for edge-based GPIO interrupts
156 - Add support for CF IDE on expansion bus
