Whats the real difference between nmi_watchdog?1 and =2? Since
nmi_watchdog=2 works here:

NMI: 9884
LOC: 80297310
ERR: 0
MIS: 0

Also, wouldn't it be better to not depend on bioses and bios versions
atm, ie hardcode pin0 since Allen Martin stated that it's hardwired on

ie, just:
if(pin2 && nforce2_chip)
printk("ALERT: Known defect in bios, mail your manufacturer. Using

Since this whole problem is pissing me off... It would be much better if
one had some kind of access to the information from nvidia so you can
just point at it, telling the mb-manuf. that they are morons and go fix
=). (Did i mention that i have had this problem for quite some time and
would have gone postal if it wasn't for Ross Dicksons fixes =))
