no usb device with 2.6.31 kernels on rawhide

[José Matos]

To make the story short I bought a new laptop, I tried to install with the 
latest installer but failed for several (already reported) reasons and I was 
forced to use the Alpha installer. FWIW I used the kde live installer 
(although this should be irrelevant in what follows).

The first time I have updated the kernel I got no usb devices working, the 
same happened with all the kernels released in the last week.

The error messages are:

Is this related with http://bugzilla.redhat.com/show_bug.cgi?id=524808 or 
should I open another bug?
