Vanilla Kernel 2.6.31.1 fails to load it87 on my machine with the same messages as posted above.

[71916.534278] it87: Found IT8716F chip at 0x290, revision 0
[71916.535783] it87: in3 is VCC (+5V)
[71916.537239] it87: in7 is VCCH (+5V Stand-By)
[71916.538763] ACPI: I/O resource it87 [0x295-0x296] conflicts with ACPI region IP__ [0x295-0x296]
[71916.540365] ACPI: Device needs an ACPI driver

In addition, asus_atk0110 loads but leaves no trace in dmesg when loaded.

Motherboard is an Asus M2N32-WS. DSDT attached.
