960px is 960 pixels. Page flipping is actually double buffering, used
on the Y axis, meaning that the framebuffer actually holds 640x480
twice, thus 640x960 pixels, and switching from one part of this bigger
frame to the other to do page flipping.

You should see something like:

xres = 640 px
yres = 480 px
xres_virtual = 640 px
yres_virtual = 960 px
