I played around more with my laptop yesterday and came up with this:

The weirdness in X is caused by having drm compiled into my kernel,
if I remove drm, S1 works fine again.  Even if I suspend/resume in
single user and then try to start X in multiuser after resuming X is
still hosed.  I thought for a while S1 wasn't working because ata1
takes a _long_ time to reset its' devices even though I have no
devices on ata1.  (I have a removable CD drive that hooks up to ata1
when it is inserted.)  I haven't tried with the CD drive hooked up
to see if that shortens the reinit time for ata1.

S3 is a more complicated story.  I have never gotten it to resume
ok on my laptop except that during one set of tests yesterday in
single user, it did work ok with the kernel with drm compiled in.
Today during my tests, I can't get S3 to resume ok in single user
mode either with the drm kernel or the drm-less kernel.  Both
kernels were with yesterday's sources btw.
