After playing around a bit, my Aspire One (v3114) got bricked after a normal reboot (blank screen, power led and fan on, nothing else). There's a nice recovery procedure for the BIOS at macles.

Somehow an A150L with the v3114 BIOS didn't let me update it to v3304. The Power-LED was blinking and the LED on my flash drive flashed but after a few seconds, the A150 rebooted and the BIOS reported still the v3114.
I'm not sure whether this is neccessary as I don't remember doing it when recovering my bricked A150X ↩
