Do a grep for nforce and you'll find:
[PATCH] fixup for C1 Halt Disconnect problem on nForce2 chipsets
Based on information provided by "Allen Martin" <AMartin@xxxxxxxxxx>:
A hang is caused when the CPU generates a very fast CONNECT/HALT cycle
sequence. Workaround is to set the SYSTEM_IDLE_TIMEOUT to 80 ns.
This allows the state-machine and timer to return to a proper state within
80 ns of the CONNECT and probe appearing together. Since the CPU will not
issue another HALT within 80 ns of the initial HALT, the failure condition
[ACPI] workaround for nForce2 BIOS bug: XT-PIC timer in IOAPIC mode
"acpi_skip_timer_override" boot parameter
dmi_scan for common platforms, may be replaced with PCI-ID in future.
So it's only missing the patches that ross mentioned, it will still work
without em. (except for clock drift afair)
