I don't have my laptop with me, but I just did the following text
substitutions (using sed) on the ASL DSDT:

"*PNP" -> "PNP" (per Christoph)
"C11C" -> "BAT1"
"C11B" -> "BAT2"
"C11A" -> "ACAD" (I'm not sure about this one --
check your /proc/acpi/ac_adapter dir first)

It was working well until I fixed my DSDT!

Interesting that you have a /proc/acpi/sleep entry; I don't. I've
been using "echo -n '1 0 0' > /proc/sys/kernel/swsusp". It just
occurs to me that I should turn on the debugging bits and see
if I can understand what's wrong ...

This should be repaired once you tweak the DSDT.

Please report back how it goes -- I'm using the 20020709 series of
patches on kernel 2.4.18, so if everything works out for you I
might upgrade to 20020726.
