I tried everything. The simple truth is that you are not guaranteed a consistent result with these boards. Either it will work, or either it won't. And the only explanation I can give is that it has something to do with voltages and what kind of Northbridge you got. Maybe on the boards that it does work on, the NB can tolerate a lower voltage. Who knows. The Foxconn G45M-S BIOS showed a little promise, but it stalls at "PCI IRQ Routing Table Error". It's not a hard stall but a system halt. I tried copying the routing table from the Dell BIOS to the Foxconn, but that only showed the routing table error at a different address. I also tried repositioning the sticker and shaving off more of the sticker plastic so that it fit better. Didn't help. I tried flashing with AFUWin with all options ticked, no dice. As I mentioned, and as a previous user has tried, I flashed the BIOS externally with a programmer. I might try an E5430 I also have and see if that works. But I doubt it. Look for another board if you plan to do this mod. EDIT: No go with the E5430 either.

I flashed the chip externally after re-modding the BIOS. Same result. It's very slow and Windows 7 won't boot up. This is G45A01 board revision A00. So there's definitely something awry.

I am in the same boat as you stojke, except with the Vostro 420 and the G45A01 (not sure which revision). But it shares the same BIOS with the 220. The stepping isn't the issue, because I've tried it with the SLBBM E5450. Startup is extremely slow. I've got the BIOS out of the socket now, and I'm going to try to flash it externally, like you did. One thing about the 220/420 BIOS is that there is no automatic fan control... It seems like Dell just went ahead with an unfinished, unlicensed AMI BIOS for these models. I'll report back.
