Question Dell Latitude E6500 w/ kernel 2.6.27: Missing /proc/acpi/event


I'm just setting up my new Dell latitude E6500 with Fedora Core 9. Suspend seems to work, but when I re-start the screen stays blank and there's nothing but the occasional disk access going on. "Blind" re-booting with ctrl-alt-del doesn't work and I have to power-off and restart to get it running again. On investigating, I found that the acpid initscript wasn't running. If I try to run acpid manually it reports:
acpid: can't open /proc/acpi/event: No such file or directory
and indeed /proc/acpi does not have an event file or directory. I've checked my kernel config and I've got PM, ACPI and suspend to RAM configured in there, so I'm at a loss ass to why I'm missing the /proc/acpi element.
Relevant lines from dmesg:

Hi, from what I've understood, much configuration is being migrated to sysfs, and, this migration being new, not many programs support calls via sysfs. For acpid you have to enable legacy /proc/acpi/event (ACPI_PROC_EVENT=y in your .config file).

PS: I'm not sure it's a good idea to post all your personnal details in your signature...

Thanks. I wasn't seeing that option in gconfig (maybe I'm blind, maybe it's not showing). I'll try a recompile, but this makes sense so should hopefully fix it. Ah, legacy interface issues :-).
