I can send you the full dmidecode, a subset is available on the thinkwiki:

not sure.  I can't seem to find any info about the s30 bioses on lenovo's pages.

I've pretty much figured out what needs to be done, I've just been too
busy to grab the latest kernel ibm-acpi code and make a patch.  It's
pretty similar to the 570.  the ec and the vid have slightly different
handles:
ec is at _SB.PCI0.ISA.EC0
video is at _SB.PCI0.VGA
most of the rest looks pretty standard.  Brightness would be nice, but
I don't see any relevant handles.  If you see any other interesting
things hidden in the dsdt, I'd be interested.

Thanks

Alex
