Hope it works for 0 :) (yes it seems it works)

All good. Works:
Vendor ID: ASUS, part ID: M2V-MX SE
DMI string system-manufacturer: "Bochs"
DMI string system-product-name: "Bochs"
DMI string system-version: "Not Specified"
DMI string baseboard-manufacturer: ""

DMI string baseboard-version: ""
Mapping VT8237S MMIO registers at 0xfed02000, unaligned size 0x70.
DMI string chassis-type: "Other"
Found ITE Super I/O, ID 0x8712.
