Yes, that is the same as my config.

I had this set to be compiled into the kernel.  Should that present
any problems?

I had this enabled (compiled into kernel) since I do own a IBM X40.

What on earth is this?  I read the descriptor, but it didn't help me much...

I'm just going to try compiling stuff into the kernel first, before I
try and tinker.

So, I should rename one of my kernels and try and see which one is
which?  Or am I still off the mark?  It didn't look like it compiled
the kernel...  I think it should have taken longer, but it didn't.  I
may be missing a step.  : /

Just a question: if the support is made to be as a module (M, instead
of *) does that mean that you have to add something like "doacpi" to
the boot parameters?

Ah, you take crazy-pills too.  I've already taken mine, so I'm a
couple minutes away from sleep.  Thanks for your help.  By the end of
this I'll hopefully be guru enough to help someone else out in turn :
