There has been a lot of work on the fxp driver over the past couple of
weeks. It's working for my with a kernel built from sources I cvsuped
yesterday morning. This is a problem lots of people have
reported. Hopefully fixed.

My T30 is not a maestro3. It's an ICH/AD1881A. You need devices ichsmb,
smbus, smb, and pcm. I have never tried loading them. I build them into
my kernel, but they should work OK if loaded.

Use apm. It works quite well, although you will need ps2 (available as a
floppy image from the IBM web site) to configure it. The IBM ACPI is
broken at this time. I have seen a claim that IBM will have an update to
fix it soon, but I cannot confirm this.

Finally, remove "device eisa" from your kernel. It can cause weird
behavior on the T30.
