["Paul Rolland" <rol@as2917.net>]

Hello,

Good news !
Using the patch : 
http://www.brodo.de/cpufreq/cpufreq-2.5.54-p4-1
it is now booting fine !

1 [11:40] rol@donald:~> cat /proc/cpufreq 
          minimum CPU frequency  -  maximum CPU frequency  -  policy
CPU  0       302902 kHz ( 12 %)  -    2423222 kHz (100 %)  -
performance

Cool...
