ACPI headaches.. acpid there, but /proc/acpi missing?

[MDesigner]

I've been trying to get ACPI working on a laptop running Slackware 10. I compiled the 2.6.7 kernel myself, with ACPI options compiled into the kernel. I boot up, and there's /usr/sbin/acpid.. but I can't run it cuz it can't find /proc/acpi. Am I missing something here?

Did you build these into the kernel or as modules? You'll have to manually load the modules for /proc/acpi to appear... if they are built into the kernel I'm not sure why acpi isn't working...

If you didn't compile in legacy /proc/acpi interface support that won't show up. It was moved to the new sysfs (don't remember the exact path right off hand /sys/something/or/other), and /proc/acpi is deprecated so you should probably move to the new one anyway if possible.

Ah, no wonder.. I saw a sneaky err msg in my log which said my BIOS is from 2000 and too old to support ACPI. (that's almost literally what the msg said.. I got a kick out of that) :)

I get a similar message on boot about the BIOS AML being broken or something, but it still works fine. Mine is from 2002 though, so it is a little newer.
