i915 ("Intel Graphics Media Accelerator 900") troubles

[steve]

I am (trying) to get X running on my recently purchased hp pavilion
4030us, which uses the "Intel Graphics Media Accelerator 900" i915GM
chipset. I was unable to get it to recognzie my card
with X 6.8.2 so based on
http://lists.freedesktop.org/archives/xorg/2005-April/007247.html I
downloaded the  latest X.org snapshot
(http://xorg.freedesktop.org/snapshots/xorg-x11-6.8.99.5.tar.bz2) and
compiled and installed that, which succeeded.  However it still does
not recognize
my card (or my x config is wrong, or something).

kernel: "hardened" Gentoo 2.6.11
(which means I am using PaX and dllloader and have compiled
significant portions of X with "-nonow" flag to ensure lazy loading --
but all of X seems to load correctly so I don't think this is causing
issues)

loaded modules: http://mirrorshade.net/logs/lsmod.log
xorg.conf: http://mirrorshade.net/logs/xorg.conf
lspci output: http://mirrorshade.net/logs/lspci.log
X -scanpci output: http://mirrorshade.net/logs/scanpci.log
X output (X -config xorg.conf): http://mirrorshade.net/logs/x.log

I've fiddled a bit with the xorg.conf (changing with device to use in
screen0, which modules are loaded, some device options,...) to no
avail. Results are about the same regardless.

intel_agp, drm, and i915 are loaded.
agpgart recognizes the card (AGP aperture is 256M @ 0xc0000000)

my video controller(s) (from lspci.log):
...
0000:00:02.0 VGA compatible controller: Intel Corporation Mobile
915GM/GMS/910GML Express Graphics Controller (rev 03)
0000:00:02.1 Display controller: Intel Corporation Mobile
915GM/GMS/910GML Express Graphics Controller (rev 03)
...

This results in (from x.log):
...
(II) I810: Driver for Intel Integrated Graphics Chipsets: i810, i810-dc100,
       i810e, i815, i830M, 845G, 852GM/855GM, 865G, 915G, 915GM
(II) Primary Device is: PCI 00:02:0
(WW) I810: No matching Device section for instance (BusID PCI:0:2:1) found
(--) Chipset 915GM found
...
(II) I810(0): initializing int10
(EE) I810(0): Cannot map V_BIOS
(EE) I810(0): VBE initialization failed.
...

Is my graphics card "newer than CVS" or my kernel modules are out of
date, or I'm doing something totally wrong?  Thanks...
