Hello Guys,
I have an Intel 950 GMA video card,
built-in in my computer's motherboard.
My motherboard is D945NT.
I installed FreeBSD-6.2-RELEASE, and cvsupdated
it to FreeBSD-6.2-RELEASE-p5.
Installed my ports and cvsupdated them.
I found "beryl" in /usr/ports/x11-wm, it
seemed to depend on Xorg-7.2
I successfully upgrade Xorg-6.9 to Xorg-7.2.
I also compiled beryl, everything seems to be ok.
..and I have tried to make it work, I give up.
The problem seems to be that X is
trying to find /dev/agpgart, according
to my /var/log/Xorg.0.log:
(II) I810(0): VESA VBE OEM Vendor: Intel Corporation
(II) I810(0): VESA VBE OEM Product: Intel(r) 82945G Chipset Family Graphics Controller
(II) I810(0): VESA VBE OEM Product Rev: Hardware Version 0.0
(II) I810(0): Integrated Graphics Chipset: Intel(R) 945G
(--) I810(0): Chipset: "945G"
(--) I810(0): Linear framebuffer at 0x40000000
(--) I810(0): IO registers at addr 0x50100000
(==) I810(0): Write-combining range (0x50100000,0x80000) was already clear
(II) I810(0): 2 display pipes available.
(II) I810(0): detected 7932 kB stolen memory.
(EE) GARTInit: Unable to open /dev/agpgart (No such file or directory)
(WW) I810(0): /dev/agpgart is either not available, or no memory is available
for allocation. Using pre-allocated memory only.
(--) I810(0): Pre-allocated VideoRAM: 7932 kByte
I have seen beryl working on Gentoo Linux,
/dev/agpgart is present in an identical system,
and it seems to me that it is not a problem
of memory allocation.
so...
What do I have to do to create /dev/agpgart?
My kernel has
device agp
present.
Thank you in advance.
Eduardo.

It looks to me like you don't have working dri/drm. You have to have direct rendering working before you can get beryl working. AFAIK, drm support for your chipset is not available in 6.1-RELEASE, and the drm module is what provides the agpgart device.
sys/dev/drm/drm_pciids.h on 6-STABLE from about February shows this:
#define i915_PCI_IDS \
{0x8086, 0x3577, 0, "Intel i830M GMCH"}, \
{0x8086, 0x2562, 0, "Intel i845G GMCH"}, \
{0x8086, 0x3582, 0, "Intel i852GM/i855GM GMCH"}, \
{0x8086, 0x2572, 0, "Intel i865G GMCH"}, \
{0x8086, 0x2582, 0, "Intel i915G"}, \
{0x8086, 0x2592, 0, "Intel i915GM"}, \
{0x8086, 0x2772, 0, "Intel i945G"}, \
{0x8086, 0x27A2, 0, "Intel i945GM"}, \
{0, 0, 0, NULL}
So you have to have the i915 module loaded to use this chipset. Though the i915 driver was ported for 6.1-RELEASE there was no Makefile included, and it never really worked until after 6.2-RELEASE. Personally, I'm tracking 6-STABLE and I've had drm working with an i845G since February of this year when anholt MFC'd a load of i915 drm changes. See this log for more info: http://www.freebsd.org/cgi/cvsweb.cgi/src/sys/dev/drm/i915_dma.c
