Manually geotagging using GPS coordinates - not location names?

Question

I recently came back from a vacation in Oregon where I took close to 1000 pictures. Since I knew it would be difficult to remember the exact location of every picture, I brought along a standard GPS and took a snapshot of the coordinates displayed on the screen at each location I took pictures. I probably should have tested my theory first, but I assumed I could just plug the GPS coordinates manually into iPhoto. It turns out I can only use a location name - not coordinates. Since most of my photos were taken away from civilization, they don't exactly have names.
I don't mind doing a little manual work to make this work, but does anybody know how I can get exact GPS coordinates on my picture? I don't really want to just type "Portland Starbucks" or something and have to drag around until I'm close to where I think the picture was taken.
Thanks for your help!

iPhoto has a neat feature called "Help"
Here is what it says about your question:
*Using latitude and longitude to add places to your photos*
If you have latitude and longitude information for the place where you shot your photos, you can use it to add the location to your photos and Events.
To use latitude and longitude to add a place:
Select the photo or Event you want to add location information to.
Click the Information button in the lower-right corner.
This “flips” the photo thumbnail or Event tile so that you can enter information about it on the “back.”
NOTE:You can also select and add locations to more than one photo in an Event or other group, without adding locations to them all. To do so, select the desired photos by dragging or Command-clicking, move your pointer over the selected photos, and then click the “i” button for any one of them. Continue to step 3.
Select “photo place” for photos or “event place” for Events, and then choose “Find on map” from the pop-up menu that appears as you type.
The Add New Place dialog appears.
In the search field, type the latitude and longitude, separated by a comma.
For example, you can type “24, -110” or, if you prefer, you can use a longer format, such as “24.15988731, -110.50838234.” It’s important to always put the latitude first.
Look at the map to confirm the location, and then do one of the following:
If the location is correct, continue to step 6.
If the location is incorrect, you can enter the latitude and longitude in the search field again, or drag the pin to a more exact location on the map.
If you want, use the plus and minus buttons to zoom in and out, and drag the map to center it on a better spot.
When you’re finished, click the Assign button.
