Preview slow to display JPEGs

It's totally unusable when flipping through many images.
Operating system: OS 10.6.5 - completely up-to-date. Clean install onto formatted HD.
Preview.app version 5.0.1
Model Identifier: MacBookPro1,1
Processor Name: Intel Core Duo
Processor Speed: 2.16 GHz
Memory: 2 GB
Boot ROM Version: MBP11.0055.B08
SMC Version (system): 1.2f10
Chipset Model: ATY,RadeonX1600
VRAM (Total): 256 MB
EFI Driver Version: 01.00.068
Other image formats work fine. Other apps open JPEGs instantly.
I had Tiger before, and JPEGs would load instantly.
My hard drive is healthy. Console doesn't show any unusual messages.
I tried turning QuartzGL on and off, system wide with the terminal command
sudo defaults write /Library/Preferences/com.apple.windowserver QuartzGLEnabled -boolean YES
I tried copying Preview.app from the install DVD.
Here is a screen capture I made of the problem: YouTube - Image preview in Mac OS 10.6
Here is a screen capture someone else did: http://dl.dropbox.com/u/5803292/previewspeedtest.mp4
Here is him performing the same task with the same hardware in OS10.4: http://dl.dropbox.com/u/5803292/tigerpreview.mp4
I get mostly ignored on Apple.com discussion forums.
Kinda disappointed and frustrated here.
