Titolo: kernel ma che vuoi?

Ho installato Mandrake 8.1:
tutto funziona bene nonostante i casini per far partire X( la scheda video integrata
non voleva saperne)ma ora sembra tutto a posto(ho trovato i driver giusti)!
Pero` io sono uno che ha un sacco di pare e quindi sono andato a darmi un occhiata a
quello che scrive il kernel (penso) all'avvio del computer con "dmesg | more" e ho 
trovato alcune cose strane e non so se devo preoccuparmi.
Per questa ragione spero che qualche Linuxiano esperto o comunque piu` esperto 
di me(e non ci vuole molto) mi sappia dire qualcosa in modo che io possa 
migliorare la mia postazione e magari imparare qualcosa.
In particolare mi facevano specie le linee dove:
1)dice di non riconoscere il north bridge
2)quando mi da messaggi strani sull'audio alla fine
3)non e` che mi ha abilitato la DMA a 33MHZ vero?".
Se per caso fosse importante la mia MB e` una Asus A7VI-VM(con scheda audio integrata
AC97 e scheda video integrata Prosavage KM133)
Grazie a chi mi rispondera`.
(ho inserito alla fine il file generato da dmesg | more)

La frequenza del bus PCI e' tipicamente 33MHZ, da non confondersi con
le modalita' UDMA, infatti la modalita' per il tuo HD e' UDMA100.
Il filesystem di Windows e' di tipo 'vfat' in linux non 'msdos',
eventualmente correggi /etc/fstab
Per la scheda audio integrata VIA686A utilizzo i driver ALSA e non
quelli forniti nel kernel che mi hanno dato problemi. Se sei
interessato scaricali da 
www.alsa-project.org
 (in formato sorgente,
ultima release stabile 0.5.12 se non sbaglio, la 0.9beta a me ha dato
problemi), o cerca gli rpm per la tua distro, devi anche modicare il
file /etc/modules.conf e abilitare l'emulazione OSS per quelle
applicazioni che la utilizzano, leggi la documentazione e se hai
problemi io ho un tutorial che spiega passo passo come fare.

Scusami, ma era proprio necessario, riportare tutte lee 193 righe?
