Maciej,
Older PC's require this kernel boot option. Early in ACPI development many PCs didn't support ACPI and many that did implemented their own individual ACPI frameworks. Consequently, if the kernel discovers an older PC (I can't recall the cut-off date now) it disables ACPI by default. Gutsy & Hardy warn about this at boot time.
If you had this issue on a newer PC it may indicate that BIOS is not presenting it's date and other information correctly.

Clearly, you found that you must force the kernel to use ACPI and fortunately it is a usable ACPI.

This is a check to see if you are happy for this bug report to now be closed.
Thanks.
