 Ah, this is why it's called "Intel sig", I see...

 FWIW, I've opened the box to try to cool the DIMMs a bit and now the
results are

	# ./fbdt
	Intel sig at 0: 1d 11
	Current temp is: 65.000000C
	Intel sig at 16: 1d 11
	Current temp is: 0.000000C
	Intel sig at 32: 1d 11
	Current temp is: 52.000000C
	Intel sig at 48: 1d 11
	Current temp is: 54.000000C

so not only the values did diminish but there is also 54 instead of 0 for
the last one. So I wonder: could it be that the DIMMs really overheat and
the temp of the 2nd one is just out of the range?

 The files are relatively big so instead of posting them here I put them on

	http://www.tt-solutions.com/vz/hardware/tyan2696/pci.ls
	http://www.tt-solutions.com/vz/hardware/tyan2696/pci.dump

Please let me know if you need anything else. I'm afraid I don't really see
anything helpful in lspci output on my own.

RM> Do you have the windows software somewhere to download?

 No, not really, I use SpeedFan (http://www.almico.com/speedfan.php) but I
don't know if it's capable of reading FB-DIMMs temperatures and, as I said,
I don't really want to install Windows on this machine just to try it out.

 Thanks!
