Have you tried swsusp, which is included in the vanilla kernel? I'm currently
using vanilla kernel 2.6.12. If you're using make xconfig, select "Power
management options (ACPI, APM)" and enable "Software Suspend (EXPERIMENTAL)".
You can also set your default resume partition. I am then able to hibernate
using the acpi script
/etc/acpi/hibernate.sh
Oh, I had to set ACPI_HIBERNATE=true in /etc/default/acpi-support. I should
mention that I'm not using an IBM thinkpad, but it's worth a shot.
