    Very interesting. I was sure when you got your new kernel you lost 
the kernel driver for your video card. This happens always with Nvidia 
unless you get a new driver upgrade too. I hope Ubuntu has this feature.

    I think the splash problem is a problem with the Nvidia software. Of 
course both the splash and Nvidia modules are picked up by the kernel 
and they must interact in poor ways :-)
