There may be a better answer to your question, but here's my first thought:
Render the border pixels like this:
1) Measure the distance between you're camera and it's target.
2) Now dolly the camera back say 10% of that distance to obtain a 10% border
pixel boundry.
3) Calculate the new resolution by X = X * 1.10 and Y = Y * 1.10.
4) Render the scene to the new resolution using the NULL device.

5) The idea here is kind of like matting a picture using Video Post. The idea
is to place the larger rez rendering behind a "hole" that's cut to exactly the
normal resolution you need. Do this by using VP to offset the larger images so
that their center falls in the center of the normal rendering area. Or -0.5 *
(X2 – X1). VIOLA!
Example using PAR resolution.
1) Distance from camera to target is 100 units.
2) Dolly the camera back 10 units.
3) New resolution is 752 * 1.10 = 827 and 480 x 1.10 = 528.
4) Render using Null device to disk files at 827×528. (aspect stays the
same)

5) Put the renderer resolution back to 752 x 480.
Create an IFL of the larger files you rendered in step 4.
Enter VP and create exactly 1 entry for IFL.
Edit the entry and use the OFFSET button at -.5 * (827 – 752) = – 38 for X
offset.
Use the same formula to get -24 Y offset.
Render again. Be sure all color correcting is OFF including GAMMA
correction.
Cheers.
