Funny, because I was about to ask the same question regarding the T61p.  

I have heard that SMP prevents suspending entirely, but turning off the
second CPU via BIOS doesn't help.  I have been using acpiconf -s3 to test.
Each time I get a console message saying that suspend event failed. Never
does it suspend, nor does it seem to bother the current state.  I can
continue working normally.

I get the same ACPI warnings and "failed" as you.  My acpi0 has <LENOVO
TP-7L> though.

I'd be happy to provide more information or do some spelunking if need be.
