FYI: Since the X61 and X61s seem to have a lot in common, and I just
went through two days getting 2.6.24 to work correctly on my X61,
thought you might benefit from my results. In particular, the default
for "acpi_osi" changed between 2.6.22 and 2.6.24 so you now need to
explicitly ask for it rather than getting it by default and on my 7675
X61, you need it, along with several other options.

Suspend/resume works from text console & X using S2RAM_OPTS="-f -a 3"

Linux is SuSE 10.3 using SuSE "kernel-default-2.6.24-32.1" with disk
protect and tp_smapi patches.

X61:~ # s2ram -i
This machine can be identified by:
    sys_vendor   = "LENOVO"
    sys_product  = "7675CTO"
    sys_version  = "ThinkPad X61"
    bios_version = "7NET30WW (1.11 )"
See http://suspend.sf.net/s2ram-support.html for details.

If you report a problem, please include the complete output above.
X61:~ #

Note that the following additional kernel options are also needed:
  pci=routeirq
  irqfixup
  acpi_osi=Linux  
The first two to get the right side USB ports and SD card slots to work,
the last to get resume & hibernate to work. 

Good luck and have fun!
