intel d945gclf(latest 0278 bios) fixed dsdt

[Evgeny Petrov]

It seems i finally got rid of annoying  acpi bug in d945gclf. It showed
itself as a 50% cpu usage by system process and repeating errors in system
log:

+ACPI Error: Method parse/execution failed [\\_SB_.PCI0.LPC_.SMBR] (Node
> 0xfffffe0002463000), AE_AML_INFINITE_LOOP (20110527/psparse-560)

​I use FreeBSD 9.1-RELEASE-p19, but before that there was Windows XP
installed on this machine and the same behaviour was there too.

I can not be 100% sure, but two days uptime and it's working fine so far.​
​Used the info from here <https://bugzilla.kernel.org/show_bug.cgi?id=14552>​,
it worked for them too.
I'll drop a note here if the bug would return.
