problème d'ACPI sur Compaq Presario

Bonjour à tous!

Je possède un ordinateur portable Compaq Presario 700UK et j'y ai
installé la Linux Mandrake 9.2 (enfin la 9.1 updaté à 9.2) et
malheureusement pour moi, l'ACPI ne fonctionne pas (problème ... mon
portable est 100% ACPI). Je me suis renseigner un peu partout mais je
n'ai pas trouvé de solution:
J'ai commencé par essayer d'activer l'acpi au boot (acpi=force), de
désactiver l'APIC (noapic) et l'APM (noapm) mais mon ordi ne demarre
alors pas du tout :( dès que je force l'acpi (les autres commandes
seules ne font rien!).
J'ai verifié la config de mon kernel et l'ACPI est bien activé!. Sur
certains site ils conseillent de patcher le kernel et de recompiler le
noyau, j'ai alors voulu patché mon noyau mais il semble (je ne suis pas
sûr) qu'il soit déjà patché!! (j'avais un message comme quoi le patch
était déjà appliqué), et la version du patch semble correcte (kernel 9.4.22)
Voici le résultat de la commande "dmesg" (je vous met tout au cas où
vous trouvriez un autre problème ;):

Apparement le problème viendrait du BIOS ;_;
Si quelqu'un pouvez m'aider à résoudre ce problème car mon portable
tourne à fond en permanence et je ne pense pas que ce soit bon pour sa
santé.

Merci d'avance.
