Hi,
         No luck.  I have a X58 board that also does not work, but in 
a different way

ichwd module loaded
ichwd0: <Intel ICH10R watchdog timer> on isa0
ichwd0: Intel ICH10R watchdog timer (ICH10 or equivalent)
ppc0: parallel port not found.

watchdogd starts up fine, but a kill -9 to it does not result in the 
box resetting.


isab0 at pci0:0:31:0:      class=0x060100 card=0x4f538086 
chip=0x3a168086 rev=0x00 hdr=0x00
     vendor     = 'Intel Corporation'
     class      = bridge
     subclass   = PCI-ISA
     cap 09[e0] = vendor (length 12) Intel cap 1 version 0
                  features: SATA RAID-5, 4 PCI-e x1 slots
