That sounds like a overly broad statement. How do you know
it affects all Asus boards and not just your specific BIO version?

We already should disable it on NF5 automatically. Timer override was all
broken on NF3/NF4, but apparently works on NF5 again.
But the check relies on HPET being present. Maybe Asus "forgot"
to set up the HPET table again and the test fails.
[In general Asus BIOS writers seems to have issues. They completely
broke all the MCFG tables too]
I can't say from the URL above if it's that because it's missing a complete
boot log. Marc, please add that.
Andy, I guess the timer override check just needs to be tightened to check
the specific PCI IDs of NF3/NF4 only and not rely on HPET being right.
Do you have a list of them?
I suppose we also need a no_acpi_skip_override setup option for future
cases.

Just by logic it's impossible because all 64bit systems are regular
PCs too @)
Anyways, there is cruft, but it is new cruft replacing the old cruft,
so overall there is less cruft.
