I think my video card is having problems with the clock speed and
interlaced mode.  This modeline:

Modeline "640x480i" 14.16 640 712 776 904 480 532 537 625 interlace
-hsync -vsync

came from here:

http://www.sput.nl/hardware/tv-x.html

I've been experimenting with the above modeline, but I changed
640x480i to 640x480 so the VBIOS will accept it.  xorg won't start if
the clock speed is less than 26.  It also won't start if the interlace
option is used, even if the clock is above 26.  From what I
understand, a video card needs to be able to output with a clock speed
in the 15 range and in interlaced mode for a standard TV to be able to
use the signal.

Is the video card failing when attempting less than 26 clock or
interlaced mode because I'm specifying 640x480 instead of 640x480i, or
is it because the i810's video is incapable?  Everything I read before
I tried this said almost any video card should be able to do this.

I would try to add 736x485i or 640x480i to the resolutions with
915resolution, but I'm getting this:

system1 ~ # 915resolution -l
Intel 800/900 Series VBIOS Hack : version 0.5.2
Intel chipset detected.  However, 915resolution was unable to
determine the chipset type.
Chipset Id: 71248086
