I think it could have been a coincidence, but i'd be interested in further 
details, as this is maybe a result of a "wrong" mptable setup.

Which kernel version did you use on which distribution?
dmesg output, lspci output, /proc/interrupts, and anything else which could be 
interesting. :)

Right now, not really, but i saw according to your last outputs of m57sli 
which you gave to me, that something with the interrupts is different on v1 and 
v2 and proprietary bios. This could also be a related to different bios 
versions we use, but also it could be a hardware difference which we should 
take care about.

I think for simplifying/sorting out things, it would be good if you could 
switch to the same vendor bios version that i use and resend me your 
acpidump/dmesg/lspci from the vendor bios.
I use version FG for v2 which is dated on 2008/03/07 and, i think, is equal to 
F14 of v1 which is dated on the same day.

Maybe it will be necessary to introduce some config value like:
to get the interrupt problem fixed on both versions of m57sli.
A hardware difference could also have been the reason why Soft-Poweroff didn't 
work on your v1 while it worked fine on my v2.

I hope we can avoid that step and the mistake is located somewhere else, but 
we'll see.
