Shaun,

Not directly helpful to your problem, but something I've found when making
such alterations, to guard against having to hit the big R and then having
to go through all the fsck stuff.

When you next build your kernel:
say yes to kernel hacking,
say yes to sysrq, which is the only option in that section,
then, when it's up, put the following somewhere in your start-up scripts:
echo 1 >/proc/sys/kernel/sysrq
and read /usr/src/linux/Documentation/sysrq.txt

Very useful, very useful indeed.

Only 1 thing:

What it doesn't tell you in the docs, is that when you've pressed a key
combination, the alt +print screen works like a sticky key, therefore you
must hit those keys again to turn it off, otherwise the kernel, and not
the shell, will interpret all the keys you press thereafter.
