I have this exact same problem with the exact same board with a clean install of 12.10 32 bit except that only the Ubiquity reboot fails to work. Normal reboot/shutdown works OK. None of the fixes here allowed me to use the ethernet card on this board. The warning message in /var/logs/syslog is also the same:

ACPI Warning: 0x0000000000000700-0x000000000000073f SystemIO conflicts with Region \_SB_.PCI0.SM00 1 (20120320/utaddress-251)

The motherboard came with version 1.7 BIOS which I hopefully upgraded to 1.8, which also failed. I then downgraded to V 1.6 for the BIOS and found that the ethernet card was working perfectly. The flash BIOS files can be downloaded from ASRock here http://www.asrock.com/mb/download.asp?Model=N68-VS3%20FX&o=BIOS

This combined with the alternate workaround for the later kernel allowed Ubuntu to recognise the ethernet card and use it. I then performed all (244) updates which included an upgrade from kernel 3.5.0-17 to 3.5.0-21.

After re-booting, I found that the system is broken again and will no longer recognise the ethernet card. I tried the first two work arounds again but nothing is working. There are no ACPI settings in BIOS that might help, and as stated the acpi= type adjustments in grub boot do not help at all.
