[/Sammy-ev /proc/pci ]

Moje sklepanje je bilo pravilno: kernel ne ve, kako se rece tvojemu PCI
chipsetu (pri vseh stvareh ti napise 'Unknown device'). Ceprav se vedno ne
vem, ali je to res vzrok tvojih tezav s CD-ROMom.

Na primer, moj /proc/pci izgleda takole:

PCI devices found:
  Bus  0, device  15, function  0:
    VGA compatible controller: ATI 210888GX (rev 3).
      Medium devsel.  IRQ 255.
