I'm assuming that the 1 GB card would draw more power;..
Yes, but with DDR2 or 3 memory, maybe a couple of watts. High-speed DDR5 memory consumes a lot more power, and you need to consider the difference.
Lenovo has under-rated power supplies even on current systems, the AMD 6450 that can optioned requires a 400w supply, but the M91p only has 280w.
If you can find a card with DDR3 memory, that would improve performance, even if it means getting 512MB.
