For people with PCI bridge boards (Mediator/G-Rex/Promethius etc.), I am sure that you could add upto 512Mbyte RAM with a PCI RAM card (drivers for Gigabyte's I-RAM anyone?).
The I-RAM emulates a SATA device and only uses the PCI bus for power. Assuming you can rig up SATA support somehow, you could use it as a swap disk for a virtual memory system, albeit limited to those speeds.
CompactPCI RAM expansions exist, but I'm not sure where one would get same on a plain PCI card. With the rise of FB-DIMMs, perhaps some sort of generic controller card will emerge, though that's still a "bit" pricey for now.
