 I'm not 100% sure.

 Which are the sources of data for randomness? Just the touchpad?

 > Can you test again with
 http://dev.laptop.org/~dilinger/testing/kernel-2.6.25-20080810.1.olpc.0bc186239fb1afa.i586.rpm?

 First time I try to update the kernel and got this error:

 {{{
 -bash-3.2# rpm -U kernel-2.6.25-20080810.1.olpc.0bc186239fb1afa.i586.rpm
         package kernel-2.6.25-20080813.4.olpc.cc866cfe0c31220.i586 (which
 is newer than kernel-2.6.25-20080810.1.olpc.0bc186239fb1afa.i586) is
 already installed
 -bash-3.2# rpm -U --force
 kernel-2.6.25-20080810.1.olpc.0bc186239fb1afa.i586.rpm
 /var/tmp/rpm-tmp.66030: line 1: /sbin/new-kernel-pkg: No such file or

 error: %preun(kernel-2.6.25-20080813.4.olpc.cc866cfe0c31220.i586)

 }}}

 Doing something wrong?
