You might try to trade the Lo1 for a VLAN:

vlan 4000
exit

no spanning-tree vlan 4000

int Vlan4000
  description Primary Management/Peering IP
  ip address a.b.c.d 255.255.255.255

Since autostate will put this VLAN in "line protocol down" if there are 
no physical ports, you should allow it in some trunks that you expect to 
be always up.

Yes, it is an ugly workaround, inapplicable if you don't have such 
trunks. I don't think autostate can be turned off on the 3750ME, if it 
turns out to be possible, that's better.

Bye,
