Tonight I played around a bit with adding s30 support to ibm-acpi.  I
was able to pick out a few of the features, but much content is greek
to me.  If you can put dig out whatever features are available and put
together a patch, I'll test/verify it.  My dsdt is available on
acpi.sf.net and also here:
http://www.botchco.com/alex/s30.dsl
dmidecode:
http://www.botchco.com/alex/s30.dmi

here's what I know:
EC handle: _SB.PCI0.ISA.EC0
VIdeo handle: _SB.PCI0.VGA

video related: PHS, PHS2, SWIT, _DOS, CRT, LCD

hotkey: HKEY

possible fans (although do the generic acpi thermal zone functions
handle _TZ already?)
_TZ.FAN
_TZ.FA1

Thanks,

Alex
