Send me your kingdom... there's now a number of ARM devices with PCI-e buses, or SATA/NICs plugged directly into the SoC so not hanging off crappy USB/SPI/GPIO/i2c buses :-D
But are the devices Richard has those?
The Trim Slice *has* a PCI bus (apparently unusual for ARM). However mine doesn't have SATA because it's the cheaper model, and I'm not clear how the micro SD and SD card ports are routed.
The Gig ethernet is attached to the PCI-e slot on the trimslice. The SSD on the expensive model is attached via USB so is still pretty average IMO.
You need to remember that tegra2 is now basically 2 generations old :-)
