ACPI problems with HEAD and IBM ThinkPad T23

I cvsup'd from 5.0-R to HEAD and enabled ACPI to see if anything had changed
in the past 6 months.
Indeed, things have, and a few workarounds I had implemented before were no
longer needed.

However, I still got a host of errors from ACPI upon boot, and some hacks to
device.hints were still neccessary to keep my laptop functional through a
boot.

Attached are my device.hints file and a copy of the dmesg.

In particular, the things that bother me are:
1) All of the "Method execution failed" errors
2) The fact that I have to have a device.hints entry in order to see console
message upon boot.  (Without this, my system boots up silently and after
about 30 seconds, displays the familiar login prompt.)
