Great. That's the easy part (getting it to compile).

Have you tried installing pbbuttonsd and gtkpowerprefs? Alternatively,
pommed may be of use here.
But this ACPI stuff is, probably, just a peripheral matter.

Great.

That's not so great. Did you use iwconfig before ifconfig, though?
Depending on how your wireless network is set up, you may want to
install wpasupplicant etc.

Yes, it is, but debugging this will get quite harder now. I still would
suggest you to pursue the road:
,----
| git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git
| cd linux-2.6
| cp /boot/any-config-that-you-want .config
| make oldconfig
| make deb-pkg
`----
And install the deb package that is generated. (You may, perhaps, have
to install fakeroot for the "make deb-pkg" step, but that's just a minor
package).
And, if you don't delete this tree, you can periodically grab only the
small changes that go into Linus's tree and keep following it, seeing
the everything works as intended and having direct contact with the
developers.
