I have the same vendor/device IDs on the ThinkPad T43 and yet X.org's DRM loads fine here without this patch: pci bus 0x0000 cardnum 0x02 function 0x00: vendor 0x8086 device 0x2592 Intel Corporation Mobile 915GM/GMS/910GML Express Graphics Controller pci bus 0x0000 cardnum 0x02 function 0x01: vendor 0x8086 device 0x2792 Intel Corporation Mobile 915GM/GMS/910GML Express Graphics Controller With the following difference: CardVendor 0x1014 card 0x0582 (IBM, Card unknown) FreeBSD empiric.lon.incunabulum.net 6.2-RC1 FreeBSD 6.2-RC1 #2: Sun Dec 24 11:20:48 GMT 2006 bms@empiric.lon.incunabulum.net:/usr/src/sys/i386/compile/EMPIRIC i386 empiric:/var/log % dmesg | grep drm drmsub0: <Intel i915GM>: (child of agp_i810.c) on agp0 info: [drm] AGP at 0x90080000 0MB info: [drm] Initialized i915 1.4.0 20060119 DRM, GLX modules show up in xdpyinfo. By the way, there doesn't appear to be an 'ident' field for drm_pciids.h in the binaries, though I'm on 1.2.2.3. glxgears runs as expected (~260fps in default scale at 1024x768x32bpp). I tested with an application by running games/gltron, which claims 25-40fps in 512x384 full-screen. It still seemed jerky. [Except after an ACPI suspend/resume via zzz, in which case, it cains the CPU on resume and only achieves 60fps-150fps, and acpi_video cannot attach, and gltron is jerky/doesn't work properly.] Regards, BMS
