They are completely different. In fact Panasonic told me that one reason why they didn't go for a high resolution EVF for the GF1 was that the connector would need to be huge to manage the data bandwidth.
It's widely supposed that Olympus is using a new Epson 1.44 million dot viewfinder LCD, and this may use a more efficient bus arrangement (smaller connector) than the Panasonic device.
