Hmm - OK, answers own question - FF on my Mac, with a little

coughs up a file called html.css - which *appears* to contain the
defaults.
There's a bunch of others, too:
forms.css
mathml.css
platform-forms.css
quirk.css
ua.css
viewsource.css
Those are indeed the stylesheets that control how Gecko renders pages
by default. Except for platform-forms.css, which does not exist
anymore in Fx 1.5. Safari uses very similar rules, stylesheets can be
found in System -> Library -> Frameworks -> Webkit.framework and
drill down further.
Opera's defaults are hard coded in the binary and not accessible, but
look more or less like the sample html 4.0 stylesheet in the CSS 2.1
docs.
iE's stylesheets are hard coded as well, and not publicly available.
I often noticed, though, that left on its own (using defaults) that
browser can be rather helpless. It is better to specify everything
you need (margin/padding/line-height/...) to avoid problems.
Beside looking at the UA stylesheets, a good reference for the
defaults is the HTML 4.01 DTD. (e.g. p, hx, div have {display:block}
by default).
