Full of hopes, I did upgrade to the latest kernel
(2.3.99-pre6). The kernel seems sligthly better, but it is still
ridiculously easy to crash.

Let say that I have a directory with a few kernel tarballs (in
tar.gz form), or probably anything else big (few dozen MB). One kernel
is not enough, but 2 will do nicely. Add a few more kernels if you
have more RAM or just to make sure...
If I do :
cd kernels
mget *
I get :
