It certainly is. 8MB is the general recomended minimum ram for
running X11 on Linux, because you are guaranteed to get a lot of
swapping with any less than this. This is not anything specific to
Linux - the X server is simply _very_ big, so you will have the same
effect on any machine running X. If anything, the problem is less
severe with Linux because of the quality of its memory management.
However, there is really no substitute for more memory here.

You can run e2fsck with no options just to check your filesystem even
if it is mounted, as long as there are no applications writing to the
filesystem at the time. If you need to do any repairs, the best way
is currently to boot of a floppy rootdisk and e2fsck from there.
There is currently work in progress to allow checking of the root
filesystem during boot, by mounting the root readonly during kernel
startup and only allowing root to be writeable after the fsck.
In the mean time, don't worry too much about the "filesystem not
valid" messages you get from e2fs at startup. Just run e2fsck
whenever you have a system crash.
