You know what? I was wondering this a few days ago myself. It used to run on a per blog basis as we noticed that it would run at different times during the day but I just had a ticket a few days ago where we were seeing wp-cron referenced within wp-shortstat and, with some quick checking, we discovered that it was running on all the blogs at once.
I'd have to do digging for the trac ticket but Donncha mentioned once that Upgrades is run on a specific blog when the admin of that blog accesses the Dashboard for that blog. That was a while back he mentioned that but I would think it would still hold true.
I can go digging for the trac tickets if you want. On battery right now so I;'m limited.
Each blog has it's own list of cron jobs (they are stored in the wp_x_options table with a key of 'cron' ).
So all the standard cron jobs and any added by plugins are run on each blog individually. This includes core update checks, plugin checks and theme checks.
