Something to the effect of:
Driver not loaded; Module not available.

Am I NOT supposed to be using the git sources and compiling as listed

Because that sure seemed to install the 915 driver using the i810
name, and made the boot process actually load 915 correctly...

Is there something even newer than that?

I found a download on the Intel site from 2005 that was:
Surely that's not newer than git sources?...

I've also got an i915Graphics.tar.gz from I don't even know where
which refuses to install, claiming I don't have a "current" kernel.

I realize Gentoo has some lag, but how much more current than:
Linux localhost 2.6.23-gentoo-r3 #2 SMP Tue Apr 22 08:52:18 CDT 2008
i686 Genuine Intel(R) CPU           U1400  @ 1.20GHz GenuineIntel
do I have to be?...

My head is spinning from trying all these things...
