I have an R51 which is similar to what you have
(http://www.charlescurley.com/Lenovo.R51.html), and have observed
similar problems. I'm afraid the only
solution to them I've found is to fall back to the 2.6.16-1.2133_FC5
kernel. Suspend to ram works there. I haven't tried suspend to disk
recently enough on it to remember whether it works on this kernel or

BTW, check to see if your system has the power drain
problem. http://www.thinkwiki.org/wiki/Problem_with_high_power_drain_in_ACPI_sleep

Sleep control now runs through Gnome, so I'm not surprised it doesn't
work if you boot to level three.

Hmmm, oddly enough, that sounds like the video card I have, and with
that kernel I have problems.
