I have sus-to-ram working reliably on a 2669-model with ATI X300 (and I
am working on a solution with hibernate to an encrypted partition).

Start here: <http://whoopie.gmxhome.de/linux/patches/2.6.20/>.
Get a recent kernel (2.6.20.6, e.g.).
Get the latest ati-drivers, 8.35.5.

For testing suspend-to-ram, you could try unloading all the drivers that 
you can, suspend (echo mem > /sys/power/state), and resume. Then you can 
add drivers one by one to find out if any of them is causing the problems.

Passing acpi_sleep=s3_bios to the kernel may also be advisable.

I had this issues several times recently. Each time it was traced to 
alsa-drivers, so you may want to try suspending without alsa on the first 
few tries.

Are you using suspend2-patches?
