ACPI Interupts on Dell 5100

I've been looking on the forum and I've checked a number of websites and I've found information about setting up acpid on a dell 5100 to do stuff such as turn off the monitor when the lid closes. But for some reason I can't get it to work on mine. And after doing some more research it seems like it has something to do with the newer BIOS (a32). So I was wondering if there is anyone around that is running gentoo (or any linux at this point with acpid) with a new ver of the bios that has gotten acpid to work? I'm able to get information such as how charged the battery is, the current temp and acpid will run with all the rules but no matter what I do it doesn't seem to log any of the button presses or lid closings. All /var/log/acpid has is that the daemon started and how many rules it's currently running. Any help would be appreciated as this is one of the few things at this point keeping me from going all in with linux on my laptop.

<BUMP>

Anyone at all? I really need help with this... I know other people have used the 5100 with Gentoo and other distros so I'm hoping someone here can offer some advice...

well hopefully someone now will be able to help... I was for a time having ACPId events working and the monitor was being turned on and off depending on the lid being closed or not but then suddenly for not apparent reason it just stopped... I did update both acpid and the kernel to 1.0.4-r1 and 2.6.11-r9 (gentoo) respectively but the events were working fine after I updated both of those... I have checked my logs multiple times but I can't seem to find anything that I changed at the same time... has anyone run into this issue? for now I'm using the fluxbox keys file to use keys to turn the screen on and off but I would like to automate it... what's really weird is that when I open and close the lid /proc/acpi/button/lid/LID/state does change from open to closed... but for some reason acpid is just not seeing it...

Meh. Same thing happened to me, and it just stopped working.

From the 5100 guides online, it seems this is what needs to be done:
1) Add acpi_irq_balance to boot options
2) Make sure DRI is working in X (glxinfo | grep ender)

And the day after it started working, nothing I do can get it to go back. Please let me know if someone figures this out, and if so, post the kernel version and .config, and the xorg.conf as well.

Oh, and the problem is the event interface (/proc/acpi/event) is borked. So when events happen, nothing knows about it, even if the LID function works fine.

And to report my own fix... It looks like adding "acpi_irq_balance pci=routeirq" to the boot options fixes it. Give it a shot.
