I just wanna join the row of people having this annoying delay at startup. To sum it all up, the only "solution" seems to be a downgrade of the driver at the moment. So I downgraded to version 2802 and now decreased the delay from ca. 30 to 14 sec, which is quite a progress...
I am using SuSE 7.3, kernel 2-4-10 GB and a Pixelview GeForce MX 440. Hopefully NVIDIA will somehow fix this strange issue, as basically the drivers work great and as many users seem to be affected by it.
