Found and enabled local APIC! And now /proc/cpuinfo and cpuid both show APIC support. Removed/replaced power, triggered lid-switch/battery-status/etc with no issues. (The only thing that caused trouble was Fn-F10, the "eject cd" button. Never tried it under Linux before, and the cd isn't in it at the moment anyway, so I'm betting thats unrelated. But it did cause a lockup that even sysrq couldn't recover.) Not 100% clear on what the APIC does, but I'm not sure its doing it ;) PCI: Using ACPI for IRQ routing <-- shouldn't this be missing if the APIC is in use? (Full dmesg attached, for those who are curious - the unknown-scancode is for the various laptop buttons - bright/dim, vol, media, battery, etc. Except for the volume buttons the only ones that work are the ones that directly hit the hardware, ala bright/dim.) Also, for others with an I8500 who might read the dmesg log, don't get excited; thats not the wireless card they sell (Broadcom 802.11g) its the older one (Orinoco 802.11b). They'll sell you one for about $70, goes right in in place of the unsupported one. >From single-user: # cat /proc/interrupts CPU0 0: 8716 XT-PIC timer 1: 572 XT-PIC keyboard 2: 0 XT-PIC cascade 8: 4 XT-PIC rtc 9: 0 XT-PIC acpi 11: 20 XT-PIC usb-uhci, usb-uhci, usb-uhci, ehci-hcd, eth0 14: 2610 XT-PIC ide0 NMI: 0 LOC: 8649 ERR: 0 MIS: 0 After booting, building/installing alsa-modules, getting into X, etc etc etc..
