So I had an old Acekard 2i that worked perfectly on my 3DS till it bricked. Don't remember how, but I think it was because I updated the 3DS FW before the card.
I bought a new one after that and that one has been working great and keeps on working now. I'm using A9LH + AuReinand on EmuNAND 10.7 on both O3DS and N3DS XL and it is working stock, without any TWL_firm patch or TWL_slot1 uploader from Apache Thunder.
So with the use of CFW and TWL_firm patches we can use these cards again on FW...
