Daniel, Here's my dmesg output (with grep -i 'acpi'). At the end of all the [ 0.000000] entries, you'll see a line with- [ 49.870881] ACPI: Looking for DSDT ... not found!.
I don't know if this means anything. Am I missing a kernel module or something? Came up with this link - http://www.linuxquestions.org/questions/showthread.php?t=416798 but haven't had a chance to try it out yet. ==Start of dmesg output grepped for 'acpi'== [ 0.000000] BIOS-e820: 000000007fff0000 - 000000007fff3000 (ACPI NVS) [ 0.000000] BIOS-e820: 000000007fff3000 - 0000000080000000 (ACPI data) [ 0.000000] ACPI: RSDP (v000 Nvidia ) @ 0x00000000000f7580 [ 0.000000] ACPI: RSDT (v001 Nvidia AWRDACPI 0x42302e31 AWRD 0x00000000) @ 0x000000007fff3040 [ 0.000000] ACPI: FADT (v001 Nvidia AWRDACPI 0x42302e31 AWRD 0x00000000) @ 0x000000007fff30c0 [ 0.000000] ACPI: SSDT (v001 PTLTD POWERNOW 0x00000001 LTP 0x00000001) @ 0x000000007fff9880 [ 0.000000] ACPI: MCFG (v001 Nvidia AWRDACPI 0x42302e31 AWRD 0x00000000) @ 0x000000007fff9ac0 [ 0.000000] ACPI: MADT (v001 Nvidia AWRDACPI 0x42302e31 AWRD 0x00000000) @ 0x000000007fff97c0 [ 0.000000] ACPI: DSDT (v001 NVIDIA AWRDACPI 0x00001000 MSFT 0x0100000e) @ 0x0000000000000000 [ 0.000000] Nvidia board detected.
