Have you set the following config option:

  CONFIG_APM_ALLOW_INTS:

  Normally we disable external interrupts while we are making calls to
  the APM BIOS as a measure to lessen the effects of a badly behaving
  BIOS implementation.  The BIOS should reenable interrupts if it
  needs to.  Unfortunately, some BIOSes do not -- especially those in
  many of the newer IBM Thinkpads.  If you experience hangs when you
  suspend, try setting this to Y.  Otherwise, say N.
