Thanks a lot, Paul, that was very helpful. It looks like I have some
work to do.

If it's not too much trouble, I'd appreciate it. In the mean time, I'm
looking at a hacked one off http://acpi.sf.net, so it's not very
important.

Interesting. It seems that the T41 has the fan presets but no methods
to use them. No standard ACPI fan device either. Does it actually have
a fan? :-) I don't think there's much I can do for now apart from
disabling the fan control.

That was to be expected. The code for the hot keys usually does
something like this:

if hot key events enabled
	generate event
else
	invoke default hot key behaviour

In this case, the default behaviour is toggling bluetooth on and
off. This should be easy to fix, though - a /proc/acpi/ibm/bluetooth
control would allow you to toggle the state from the ACPI handler for
Fn-F5.

I'll make it look for that. As Shaohua noted, though, I'm not yet
scanning the PCI bus on the dock.

Yes, although I hadn't noticed DMA was off. I found all these posts
saying that both IDE and ACPI hot plugging are basically not supported
yet, so I was happy to get docking and undocking with the CD drive
working at all...

Thanks,
Boris
