[SOLVED] Beta 2 will not boot

[5ft24]

Well, beta 1 has been running fine, original 256M model "B".
Tried an upgrade, no go.
Decided to start from scratch. Downloaded. Beta 2 again, unpacked the 7Z, and dd'd it to my SD card.
Still won't boot. Downloaded the last beta 1 I was using, dd'd it to the same card and it runs. Screen stays black when I try beta 2... Green activity LED flickers a couple times after power up, then nothing but the red power light.
Tried a different SD card as well...
Same result.
Will Beta 2 only run on the 512M model B?

Working now. Re-downloaded the 7z this morning and it was a different size from what I kept downloading yesterday. Booted up, configured, and its smooth as silk!
