Following your lead I just took a look at an ASUS EEE 1000HA
laptop's AC adaptor ( ASUS Model EXA0801XA ). The connector of the
EXA0801XA fits the XO and has the correct polarity.
The EXA0801XA is rated at 12 Volts 3A max. output.
I plugged it into my XO and the XO power light turned on. No smoke ;)
