I've just been doing further testing.

The kernel test setup consists of booting a kernel with init=/bin/sh,
and after the shell prompt appears, hitting the BIOS-magic "suspend to
RAM" key combination.

I can suspend to RAM under these circumstances:

- from LILO
- under RH7.2 2.4.9-31 kernel (with custom hacks to the APM code to allow
  NFS mounts to be unmounted before we shut down CardBus - search LKML
  for details on this)

I can't suspend under these circumstances:

- under a 2.6 kernel running any configuration, even with every driver
  including CONFIG_INPUT turned off (Kconfig hacked to allow that)
  leaving only IDE enabled, with the IDE power management disabled.
  I've even tried without IDE.

I've tried all the steps from a full configuration down to nothing with
2.6, turning off one driver or subsystem at a time.

Please note that this is my only x86 system, so I'm currently unable
to test my PCMCIA/Cardbus changes as fully as I would like to under
2.6 kernels.

The machine is an IBM Thinkpad 380XD, 64MB.  The BIOS does not have
the necessary ACPI tables so ACPI is of no use.  lspci output:
