I typically use a notebook and a WIA/PTP camera control application 
written by someone who frequents the PanoToolsNG list.  It will do a 
bracket of 6 custom exposure and aperture settings with the push of a 
button.  Can't find a link to it, so let me know off-list is you want me 
to flick you (or anyone else here...) a copy. 

I've always been wary of in-camera bracketing as it just can't reach the 
extreme ends of exposure that makes HDRI really useful.  And unless 
you've got a really solid tripod and panohead, I would stay away from 
manually adjusting the camera for each exposure, which can introduce 
camera shift if you're not careful.  Having to lug a notebook (or even 
UMPC) is a bit of a hassle, but with the above software I'm getting an 
automated 25-30 stops into my HDRs, when it's needed of course.

I also noticed someone else in this thread mentioning PTGui and having 
to stich each set individually.  The latest versions of PTGuiPro now 
auto-detect exposure sets and will build control points treating each 
set as a single image (or even attempt to align handheld sets).  There 
are similar pieces of software out there, but Joost (PTGui author) has 
been rolling new features into the software and fixing bugs so quickly 
(just check out the PTGui version history) new releases are coming out 
almost monthly.  I cannot recommend PTGui enough if you're doing any 
sort of pano work.
