When blocked, on one's own talk page one:
*can load the move form, but cannot submit (although the blocked header which is returned is malformed)
*can change the protection levels
*can delete the page, but cannot undelete (but can recreate as intended)
Additionally, when blocked, one can block and unblock other users.
*One should not be able to undertake any admin functions on one's own talk page whilst blocked
*One should not be able to block or unblock other users whilst blocked
