Why not change to the new buffer? Something like:
:au BufAdd * if expand('<afile>')==''|execute 'buffer'
expand('<abuf>')|execute
'file' tempname()|endif
This is nice, but. This works for :new (I tried BufNew),
but still does not work
for that empty buffer #1 that is created when vim is invoked without
commandline arguments.
I want it to work for the initial empty buffer, too.

IIUC, that buffer is created before sourcing the vimrc (at step 2 under
":help startup"), so apparently you're out of luck there. Try either
BufWriteCmd (q.v.) or BufWinEnter (but the latter will be triggered too
often, and your "if" will return FALSE except maybe the first time).
Best regards,
Tony.
