No joy in Mudville! 
As suspected, the modified IIfx ROM SIMM didn't boot the IIsi, but it STILL boots the IIfx! Go figure! :
I've got a IIci ROM SIMM to test somewhere in the mails ATM, so round 2 should be soon. I found out that the IIfx ROM SIMM boots a IIci. I'll test the IIci SIMM in the IIfx while I'm at it, just for kicks.
Ah well, here we go again. }
