Well, actually I'm not too lucky: I can't boot bzImage kernels with
lilo, and if my HD multicount is set to 16 I have all kinds of nasty
problems after a resume.

Since you recompiled the kernel with apm, I assume you also compiled
the pcmcia utils with apm turned?  (I'm not sure if they are on in the
Debian package the configure script checks the current kernel.)

The light goes solid you suspend or when you resume?  This is a little
different than when I use a non-APM kernel.  My PCMCIA card goes solid
when I resume, and the machine starts working again when I pull the
card.

If it's necessary, it's fine with me.  My message was just a kneejerk
reaction to what looked to me like something that was already
implemented.  (I'm also concerned about increased latency between
pressing the suspend key and the system actually suspending.)
