The problem is more likely related to the BIOS than the chipset. I have
a couple of RS482-M's here as well. One has to be booted with the
option "acpi_skip_timer_override" in order for it to keep time correctly
and eliminate some APIC errors. The other one does not need any special
flags. ACPI in general works fine on both boards, even for interrupt
routing.

>/ Intended to get systems with badly broken firmware running."/
Note that it says "broken firmware." That means BIOS in this case. I
would contact the vendor and ask them to fix their BIOS. If you do not
ask them now, they may not be willing to fix the BIOS later when the
board is no longer being sold. (I had this experience with Tyan. In
all fairness I was asking them for a BIOS fix years late.)
Have you upgraded your BIOS on the board? If you do, make sure you have
the system connected to an uninterruptible power supply. Also, a BIOS
recovery floppy may not be a bad idea. There's a super secret key
sequence that will reload the BIOS from a floppy in the event of a bad
flash. You can google that.
Vincent,
you maybe did not see Rob's mail and hints on the video4linux list.

Rob thanks!

Hi Robert,
Thanks for the forward Hermann, I am now subscribed on video4linux too.
A week ago, I upgraded my BIOS to the latest available version , that is
dated 10/17/2006 , version 6.00 PG. My rs492-m model is one with the
optionnal firewire interface (v1.0a).
May I ask you what version of the kernel are you using ? I am using
2.6.19 currently (with gentoo patches).
Thanks,
