1 I'd suggest SystemRescueCD.
2 It's upgraded quite often (currently using kernel 2.6.35-x)
3 has a ready to go X11 environment and most useful,
4 it's an up-to-date Gentoo system, so one immediately knows
5 where to look if there are any problems.
6 And it has a well documented (easy) procedure for extending it.

8 Helmut.
