AGP status disabled

Archived from groups: comp.sys.ibm.pc.hardware.video (More info?)

hi.
don't know if it is the right newsgroup, but I must give it a try,
this problem is driving me crazy.
I own a Thinkpad R50e 1834-NFG, with specs below:

--
Original description: P M 705, 256MB RAM, 40GB 4200rpm HDD, 15
XGA(1024x768) TFT LCD, Intel Extreme, 24x24x24x/8x CD-RW/DVD, Intel
802.11b/g wireless(MPCI), Modem(CDC), 10/100 Ethernet(LOM), 6 cell
Li-Ion battery, WinXP Home
--

my problem is that this thinkpad cannot "see" AGP.
see here: http://archive.kuht.it/agp.jpg

as you can see agp is totally disabled (seems not existant), I've
tried nearly *everything* from modifying PCI IRQs to open up intel
..inf files, from formatting with 2000/xp to respect driver
installation order correctly, no way.
Intel's .inf supports agp, as we can see:

but simply this peripheral doesn't show up.
video card is a shared memory one, 64mb, and I've 512mb.

I've latest os upgrades, latest bios (2.02), latest embedded
controller update, latest directx, latest drivers, even tried with
those from ibm and intel, no luck..
what's wrong here? thanks in advance.
