Hey guys,

I got a SONY VAIO notebook model VGN-FW140E.
I'd like to get my function keys working. From what I've read, I need to enable the Sony Vaio PI support, but it is only available if I'm using 32bit kernel (!64BIT=y as a dependancy):
Code:
  | Symbol: SONYPI [=n]
  | Type  : tristate
  | Prompt: Sony Vaio Programmable I/O Control Device support
  |   Location:
  |     -> Device Drivers
  | (4)   -> Character devices
  |   Defined at drivers/char/Kconfig:423
  |   Depends on: X86 [=y] && PCI [=y] && INPUT [=y] && !64BIT [=y]

Is there a way to get this running with a 64 bit kernel?

P.S.: I already got the Sonypi compatibility built into the sony-laptop driver:
Code:
  | Symbol: SONYPI_COMPAT [=y]
  | Type  : boolean
  | Prompt: Sonypi compatibility
  |   Location:
  |     -> Device Drivers
  |       -> X86 Platform Specific Device Drivers (X86_PLATFORM_DEVICES [=y])
  | (1)     -> Sony Laptop Extras (SONY_LAPTOP [=y])
  |   Defined at drivers/platform/x86/Kconfig:291
  |   Depends on: X86 [=y] && X86_PLATFORM_DEVICES [=y] && SONY_LAPTOP [=y]

I took a look in the code; it looks like you should only be using the sony-laptop driver, sonypi is a legacy one.

You should have a /sys/bus/acpi/devices/SNY6001 if it's loaded correctly.

Is there a problem with the normal function keys (F1-F12) or is it only certain ones? Those sort of things usually send ACPI events instead of keyboard events which may be why it looks like it's not working. Also acpid should be sending the unhandled button events to syslog in that case.
