I have a Z61m so some things might be different for you.

What sata drivers are you using? For me the precompiled kernel (from
debian unstable) loads the ahci module. Suspend to ram doesn't work with
that on (at least for me).

Firewire should work out of the box too.

hdaps: I just added:
HDAPS_DMI_MATCH_LENOVO("ThinkPad Z61m"),
in "static int __init hdaps_init(void)" (drivers/hwmon/hdaps.c)
It works, but I think the results are inverted.

tp_smapi: Use the just released tp_smapi-0.25
if it still doesn't work: what exactly are you trying to to? patching
the kernel source or compiling a separate module?

How about the usuall trick: switching to a text console before
suspending?
