Done, new kernels now compiled with CONFIG_MAGIC_SYSRQ.

Good to know.

I've now compiled 2.4.21 from with skas3 from debian, as
well as 2.4.21 with grsecurity (from, with medium
setting) and skas3, and tried uml again with the same sparse image
multiple times under both. I haven't managed to lock the machine up
to now even while installing quite some stuff, so maybe the problem
is already solved. If not, I'll tell you when it happens again. (I
think I'll run 2.4.21-grsec-skas3 for the near future now.)

Thanks for your help
