Have faith in ext3. Your filesystem integrity will be fine. How much
precious data do you keep on a kiosk any how?
If worried, mount the whole system read only. Have a small r/w partition
thats re-formatted on boot and created in a default state by un tarring
a tar ball. Sym link all files that need writing into there. Even
better, make it a ram disk.
Then just power off, willy nilly :) Its not windows.
I built a linux kiosk image a few years ago that ran completely of an
autobooting CD-ROM. Read only is tricky to get working, but helps with
the power off problem. This was back in the days before journalling
aswell.

Thats a good idea too. Unless you're in X.
