ok. Compiling without preempt and no highmem support and using the
echo 'shutdown' > /sys/power/disk
I managed to do some suspend/resume cycles. 

Some impressions: 

The status display is very ugly. It prints cryptic items and lots of
random .... and | that don't mean much to me. ;) 
It would be nice if it could just give a % age complete or a spinning
cursor to indicate its doing something. 

It's a good deal slower than software suspend2. Is there any plans to
add in the LZO compression that software suspend2 uses? 

With software suspend 2 I usually can do an entire suspend/resume
cycle in about 30 seconds. Thats from prompt to prompt. 

With swsup1/pmdisk (should I just call it swsusp1 now?) It looks like
it takes about 2.5 minutes to do a cycle from prompt to prompt. 

On resume there is a inital part where the display just sits there. I
wasn't sure if it was hung or not, but it was just calculating. It
would be nice if it could provide a 'this might take a while' or a
spinning cursor or status bar to let you know it's not dead. 

There aren't any bootup messages to indicate that it's
available. Would it be possible to add something like: 
swsusp1: will use /dev/hda2 to resume. 
swsusp1: /dev/hda2 is regular swap space. Continuing to boot.

Is it *always* slow? It is slow for some people and I'm searching
for reproducible testcase...

Hmm, not sure which part is that... I do not see delays
bigger than 5 seconds...

One line should be enough...
