I have been ignoring these for a couple of months and have not been
struck down by lightning from above.

There have been reports of a couple of devices not working that
sounded to me like potential IOAPIC/IRQ/etc mapping problems caused by
using bad data from ACPI tables (whether the BIOS had a bogus table or
FreeBSD a bogus parser is unknown to me).  This is rare.

In short, if it seems to work, it probably does.
If it doesn't work, try turning off ACPI in the BIOS.
