Oh, I would like to get HDMI working. I know LCD should work somewhat,
showing console. I never looked what does it take to get X or even non-X
graphics working.

But BBB definitely works. CPU runs at 1GHz, board boots from eMMC.
Ethernet, ADC, GPIO, I2C, UART works. There are few glitches related to
booting. Maybe some others. And I don't deny that you need certain
amount of hackerness to use it right now.
