No I don't for the ME, but you could start with this for the non-ME:

http://supportwiki.cisco.com/ViewWiki/index.php/MAC_Addresses_used_by_the_Cisco_3750
(seems to be 64 for physical ports, 64 for SVI)

and the way I reverse engineered that was just to run a script to
set up 500 SVIs and take a look at the results.
