I got an R51 2887-32G with the same graphics-controller and even gentoo.

Okay. This looks similiar to my problem. Whe I resume my laptop I see 
the message "Stopping tasks: |=================" and the laptop hangs.

I had it running in december 2004. But then I decided to do a 
BIOS-Update and from this moment on I wasn't able to suspend to ram anymore.

So: Yes, it's (was?) possible. All I had to do was configuring it like 
usual and adding the line acpi_sleep=s3_bios to the kernel (it was 
2.6.9-gentoo-r4).

I tried (I'm not exactly sure):
2.6.9-gentoo-r4
2.6.9-gentoo-r6
2.6.9-gentoo-r9
2.6.10-gentoo-r6
2.6.11-gentoo-r2
2.6.11.4-vanilla
with no success. I think I need to downgrade the BIOS.

Do you have any success?
Jan
