Fwiw, see <http://en.wikipedia.org/wiki/IBM_T220/T221_LCD_monitors>.
Gecko running on such a display would use multiple device pixels per CSS
pixel until recently.
(And of course iPhone 4 is 326dpi, and plenty of other cell phones are
in the 200dpi+ range; devices with that pixel density held at typical
monitor reading distance instead of right up to one's face might well
want to map multiple device pixels to a single CSS pixel).

That seems quite reasonable. ;)
