Ok, I worked it out. It seems like it's the ich4 i2c_i801 driver to blame.

I prevously had it compiled in, which resulted in totally unfunctional s3
resume. Then when I tried a kernel where that was modularized the s3 resume
started working with init=/bin/sh, but didn't work with bootparam single (due to
rc.sysinit loading the i2c_i801).

It seemed to be the udev starting, which loaded the i2c_i801 and that was the
triggering factor. Even an rmmod for it would make the s3 resume work anymore.

There's some recent discussion going on in lkml about the i2c_i801:
http://lkml.org/lkml/2006/4/19/68
but that fix is not sufficient. So currently am unable to use the i2c_i801
alltogether if I wish to use suspend-to-ram.

As a note to other nw8000 users:
I'm now able suspend-to-ram on a nw8000 running fc5 from X using the default
radeon driver aswell as the fglrx (even glxgears stay functional after suspend
cycle) using suspend2 hibernate script (but in swsusp mode), provided that I use
a recent kernel which doesn't have i2c_i801. A relatively easy approach for that
is to rename the i2c_i801.ko into something else. Frankly, I'm not familiar with
i2c busses at all, so I have absolutely no idea what will break by doing so, but
alteast the suspend-to-ram starts to work. :)
