I'm using a VGA-Componant card as well, the RCA VHDC-300. My TV is
native 1080i as well, and I have no problem getting 1080i from my
G-Force 5200U card.

However, from a CPU load, and interlace standpoint,. I'm running
960x540p, which I"m much happer with at the moment. At least until
there's more 1080i content.
