Vista - Wake from sleep mode has become very slow - please help!

I used to be able to put my pc in sleep mode and it would wake within a few
seconds of me clicking the mouse, hitting a key, etc. Within the last few
weeks (not sure exactly when) it now takes 18 seconds (give or take a couple)
to wake from sleep mode. It brings up the desktop and then kind of hangs so I
can't launch any applications, although I can move the mouse around. I have
searched the net and tried all kinds of troubleshooting, but can't figure out
what happened to cause the slow wake time.

I uninstalled some vista updates that occured within the last couple weeks -
no change. I disconnected a second internal hard drive (for media file
storage, not bootable) that I installed a couple weeks ago thinking it was a
power supply or bad drive issue - no change. I removed my 8800gt video card
and replaced it with the original 7300LE that came with my system just in
case it might be a power supply or video card issue - no change.

What else can I do to diagnose what might be causing this slow wake time?

Thank you for any suggestions you might have. This is driving me crazy since
it used to be so much quicker, woke within a few second to now taking almost
20.

System is a Dell XPS 410 BIOS 2.5.3 (current), E6420 processor, 320GB SATA
II drive, 750GB SATA II drive, XFX 8800GT 512MB video card using 169.25 vista
32-bit WHQL driver.

Just bumping this once in case it was a slow weekend and not many people saw
it - any suggestions would be appreciated. I've searched all over the place
and come up empty. Thought this might be the best place to get a reply, but
no dice. Is there a way to diagnose whether this is problem with a a bad
driver? Any one think the KB928135 patch that must be requested from
microsoft will help, or is that only for permanent hangs on resume/wake
versus a long delay? I'm starting to think I need to wait for SP1 or perform
a factory reinstall on my system. Thanks!

I just built a new Vista x64 system last weekend (my first) and it has the same problem, but worse.

When I first built it, it worked fine, but after a couple days, I noticed that it was taking 4 to 5 minutes after waking from sleep before it would do anything useful. I can move the mouse and open Explorer windows, but it seems as if the filesystem is hung and waiting for something because the disk light is on solid, but there's no noise from the HDD.

Very strange indeed.

Wanted to post that I found the solution to my particular problem.

Turns out that the problem was caused by the SATA driver acoustic management mode. When I enabled the AMM using the checkbox in the driver page, there was always some sort of delay when booting, and a really long delay when waking from S3 sleep.

When I unchecked AMM, the problem went away and everything seems to work fine now.

System details:
HDD - Maxtor 500GB SATA
driver - nVidia driver
MoBo - Shuttle SN78SH7 (nForce chipset)

Hope this helps somebody else.
