Yes, I did have to change my BOT to a lower value. My new fuses are:

low: E2
high: DA
extended: 06

I was able to get an Atmega328p (DIP) working with the internal oscillator at 8mhz using a 5v supply, but now it won't run at 3.3v. I'm wondering if I neglected something with my fuse settings, since I've been able to boot 16mhz *duino boards at 3.3v in the past... Or, maybe some weird shenanigans because the firmware is made for the surface mount 'megas...?

My fuse settings and bootloader:
    low fuses: 0xF2
    high fuses: 0xDA
    extended fuses: 0x05
    bootloader: ATmegaBOOT_168_atmega328_pro_8MHz.hex

Thanks for the help

I just figured I'd copy the old revision '168-based Lilypad's fuse bits and now it runs fine. (Though if you notice I'm doing something bad with the fuses, tell me smiley-wink )
    low fuses: 0xE2
    high fuses: 0xDD
    extended fuses: 0x00
    bootloader: ATmegaBOOT_168_atmega328_pro_8MHz.hex

Does anyone know where a nice fuse diagram for the 'megas (including the extended byte) is, and if the '168 and '328 fuse settings are the same? (it seems so from the datasheet I have...)

What's on your VOUT from the LCD? I needed to have a 4.7uf capacitor on mine for it to work. (though if it was disconnected entirely it did work somewhat)
