Intel_rng em notebook Sony vaio VGN-FJ250P

[JOAO_JR]

Olá pessoal, possuo um notebook Sony Vaio VGN-fj250p e tenho o ubuntu 7.04 com o kernel 2.6.20-16-generic.

Bem, a instalação correu td bem, já de kra reconheceu som, wireless, web cam. A placa de video é uma Intel Corporation Mobile 915GM/GMS/910GML Express Graphics Controller (rev 03) e ela ñ foi detectada. Veio com o pacote xserver-xorg-video-i810 instalado, mas desinstalei e instalei o xserver-xorg-video-intel e modifiquei o xorg.conf nas partes em negrito:

olha meu xorg.conf como está:

# /etc/X11/xorg.conf (xorg X Window System server configuration file)
#
# This file was generated by dexconf, the Debian X Configuration tool, using
# values from the debconf database.
#
# Edit this file with caution, and see the xorg.conf(5) manual page.
# (Type "man xorg.conf" at the shell prompt.)
#
# This file is automatically updated on xserver-xorg package upgrades *only*
# if it has not been modified since the last upgrade of the xserver-xorg
# package.
#
# If you have edited this file but would like it to be automatically updated
# again, run the following command:
# sudo dpkg-reconfigure -phigh xserver-xorg

Bem, depois q fiz isso, o video funcionou, instalei o compiz e td +, mas comecei a notar q quando iniciava o note, demorava um pouco pra carregar, aí descobri essas mensagens:

*Loading Hardware drivers

Intel_rng: FWH not detected
hda_intel: azx_get_response ,timeout switching to single_cmd mode

Aí comecei notar q as vezes o som dava problema (naum carregava na hora do boot) e o note ficava muito lento.

Então resolvi instalar o XFCE, e a demora diminuiu, mas as vezes o video do note fica lento.

Então pesquisei sobre essas mensagens, maas não encontrei nada esclarecedor para isso.

Achei no synapitic o pacote rng-tools, instalei numa esperança de haver tido uma solução, mas deu uma mensagem no fim da instalação:

Starting Hardware RNG entropy gattherer daemon: (Hardware RNG device inode note found)
/etc/init.d/rng_tools: cannot find a hardware RNG device to use.
invoke-rc.d: initscript rng-tools, action "start" failed

Depois resolvi carregar os módulos de intel-rng e deu isso:

sudo modprobe intel-rng
FATAL: Error inserting intel_rng (/lib/modules/2.6.20-16-generic/kernel/drivers/char/hw_random/intel-rng.ko): No such device

Pessoal, alguém tem uma solução pra isso, será um bug nesse kernel?  O que devo fazer pra corrigir esse erro? a config do xorg.conf tá errada?

Agradeço se alguém puder me ajudar.
