My laptop also has a spindown (five min from memory) and I have yet to have a problem with it. Don't know if any of that is "spindowns without laptopmode" in a useful sense.
Unless you can also reproduce the failure... no, probably does not help
much.
Okay, let's recap.

* There are a lot of people who are not having problems. The people who *are* having problems can usually reproduce them. My interpretation: the problem is triggered by some hardware and/or kernel config settings.
* A significant proportion of the people who *do* have trouble see 
messages about DMA timeouts. The problems do also occur on other 
hardware, but seem to be most pronounced on Thinkpad T40s. On those 
machines, the DMA timeout problems are triggered *especially* when the 
madwifi drivers are loaded (see 
http://bugzilla.ubuntu.com/show_bug.cgi?id=6108).
Perhaps I should start collection kernel configs and hardware specs, see 
if there are any unexpected commonalities. The influence of the madwifi 
drivers suggest that we could be be looking for anything really. What do 
you think?
