i have suspend installed as part of the SuSE Linux 10.1 on my Lenovo Thinkpad T60.  suspend to ram does not work by default and the machine is not in the s2ram whitelist.  below is my s2ram -i output and the options that allow it to work:

sudo s2ram -i
This machine can be identified by:
    sys_vendor   = "LENOVO"
    sys_product  = "2623D6U"
    sys_version  = "ThinkPad T60"
    bios_version = "79ET60WW (1.05a)"

s2ram -f -a 3

i actually got it working by tweaking the /etc/powersave/sleep file but it's functionally equivalent to the s2ram flags above.

i also looked in the HEAD version of the whitelist.c file to ensure there wasn't a more up-to-date entry that would match my T60.

cheers,
