mainboard/lenovo: add Lenovo Z61t laptop
This platform shares most hardware components with first-gen Core
Lenovo laptops such as T60/X60, with much smaller EEPROM size as
one of notable differences. The port features Intel graphics,
ATI-based version should work with vendor VBIOS.
Tested peripherals:
- sleep/resume,
- USB ports,
- ACPI Fn key bindings/volume buttons,
- backlight control,
- ethernet,
- wireless (under Linux),
- sound/beep,
- dock handling,
- serial via dock.
Untested peripherals:
- IrDA,
- parallel port,
- PCMCIA,
- S-Video port,
- modem,
- FP reader (should just work),
- IEEE1394.
Linux 3.16 works with native gfxinit perfectly, with Intel VBIOS
console sometimes displays nothing when i915 framebuffer is used.
Windows 7 has an interrupt assignment issue with iw3945, otherwise
tested stuff is fine.
