Well I found the unit in the FCC database

Unfortunately, Kobo has requested confidentiality on some of the submitted data until August 16, 2011.
The link is
FCC Database - FCC IDZJLKOBON905
What is interesting is that on (for instance) the Kobo Wifi the applicant in the FCC was Netronix Inc; for this unit the applicant is Kobo.
If the sample label is correct, power consumption is now listed as 5V 0.8 A compared to the Wifi being 5V 1.0 A.
