My word, that was a nice video. And it looks like a nice piece of kit. I think if you could make it work it'd be awesome.
The
Gentoo wiki says that the built in Intel 915GM card is supported by XGL so you are a lot of the way there. I'm not so sure about that 1.2GHz processor, perhaps someone with experience of XGL can comment, but maybe you'd just not be able to use the most advanced eye candy. Even a subset of features would still be amazing though.
Someone else has already
set up the P1510 with linux so a lot of the features seem to be supported or otherwise kludgeable.
Installation of linux can apparently be done via network boot. The only thing that would bug me is the trackpad driver is a bit of a hack, but it does seem to work well.
If you do this then I have no doubt lots of people here will help.
Let us know how you get on,
Chris...
