There is a nice thread on the ACPI-devel mailing list (see below)
concerning Suspend-to-Ram on Sony Vaios, and 2.6.9-final seems to have
many improvements regarding S3.

Here attached but also accessible here:
http://sourceforge.net/mailarchive/message.php?msg_id=9822400
is a mail from Luc Saillard with a Z1RMP and a vanilla 2.6.9-rc4.

Luc, did you try 2.6.9-final? 
Mark, which kernel is Fedora Core 3 test 3?

Nicolas

For the first time, with a vanilla 2.6.9-rc4, S3 works on my laptop. It's a
Sony PCG-Z1RMP. If I echo 3 > /proc/acpi/sleep while i'm in console, resume
doesn't light on the screen (radeontool has the same problem). I can reboot,
send command on my shell, but if I start X, my laptop freeze.
If I'm under X, suspend and resume works but if i go to console text screen
is black of bad video resolution.

I've also a problem with kmalloc(GFP_KERNEL) and resume while interrupt is
disabled.
