Hey Robert,

AFAIK, even in the newest release the nvidia closed driver doesn't
support PM events - ACPI included, but eventually they will. Now for
your cpmcia cards: You need the lates acpi patch form the intel's
developers site - don't remember the www address though so you might
want to go to and see it there. With it, the pcmcia
discovery and irq assignment work properly, you have to compile pcmcia
allways as modules though (I remember a message on their mailing lists
stating that it wouldn't work if compiled if pcmcia stuf is compiled
into the kernel). From the ACPI options xou have to check everything
with <y> (nothing as module). The patch is called acpi-20011205.diff.gz
and is made for the vanilla 2.4.16 source, but it applies cleanly to
2.4.17 too. I use it now with 2.5.2-pre3 thoug I had problems with one
file when applying - had to manually c'n'p a few lines of code. But it's
easy and it works.
That's the onyl chance to make acpi work with a newer kernel and pcmcia
- even on my *older* Inspiron 8000. And you will need the latest acpid
daemon too.
What you will get is proper ACPI events and status reading for battery
and ac power and stuff, and you can define/customize the actions which
acpid will attend on any event you want. So you might want to give it a
try.... The only thing is..... I still don't know how far the most
drivers are in converting from APM to ACPI management scheme....
