I don't know the ACPI details, but as far as dyanmic-hz is concerned I seem to recall I tested it with HZ=10/25/50/... too (as well as HZ=2000/5000...), everything will work flawlessy but any number below <50 will pretty much guarantee not to show even an animated flash or gif fluenty ;). Said that you can use X just fine, not only the console (my X usage on the laptop sure doesn't need a fast HZ for example).
