    OK, the computer boots with LPT enabled:

    This is somewhat confusing because after booting with the regular

    which claims to be a different superio chip. However the main point is
    that LPT is enabled by the bios and disabled during the regular boot.

    this is a regular PC. I renamed the irda-module, but that didn't help.

    This machine has a usb keyboard, but I always get a few console messages
    about a missing AT keyboard. Likewise, the audio system is functional,
    but produces a lot of warnings and error messages - perhaps there are
    some unnecessary modules being loaded. However, lsmod seems to list
    things that I expect to be there...
