I believe any half-height WiFi card will work in the 1010 or 1011. The Intel 5100 and 5300 are available in both full and half-height versions.
As holmes noted, the 5300 expects 3 antennas, while the 5100 expects 2. I expect the 1010 normally has 2 antennas installed from the factory, but if there was the option for a improved WiFi card (???), it may have come with 3 antennas.
I opted for a full-height 5100 in my Mini 9, but the 5300 should be a good choice with a third antenna, and since your netbook takes half-height cards, you could even use a newer Intel card instead: the 1000, 6200 or 6300 (3 antennas).
