Alu 21" iMac 10.6.8 (32-bit), same thing. No fix yet :-/
They can be empty folders without special icons, if there are enough and it's in
icon view, CPU spikes.
Some things I noticed.. sometimes the CPU will drop to normal levels if you
change the window size so not all icons are visible, or if you increase icon
size to reach the same effect.
 Sometimes after playing around they will /stay/ low even after making the
window larger than needed, with icons at smallest size. But if you then zoom the
window to make it "just large enough" -> spike.
 Similarly, if it stays low even after changing window & icon sizes and
settling on large window/small icons, it'll spike as soon as you switch to
another application.
 I have no idea why these things are so, but maybe they'll help someone more
knowledgable figure out in which direction the problem lies..

I can't duplicate this behaviour on a new empty account on the same computer,
but on a regular-use account on another iMac it also happens, so I guess it's
something in my setup. 3rd party prefpanels that I have on both computers: Flash
Player, GeekTool, Growl, LiteSwitchX, MacFUSE, MenuMeters, Perian & Secrets. One
day I'll try disabling subsets of those and see if one [combination] causes it..
