intel video card problem

[jls]

Hi
I've this laptop: dell latitude e6410 with an intel ironlake/m chipset video.
lspci shows:
00:02.0 VGA compatible controller: Intel Corporation Arrandale Integrated Graphics Controller (rev 02)

If I attach an external monitor to the vga port 3d works, while with the laptop monitor when  the graphics-2.6.33.3-tinycore.tcz is loaded the screen goes black and return ok only when xorg starts and in Xorg.conf the vesa driver is specified.
If in the xorg.conf I specify intel or I remove xorg.conf the screen remains black.
I repeat no problems with an external monitor.
With the external monitor I notice that the resolution changes during boot time after loading graphics-2.6.33.3-tinycore.tcz.
I've tried to add i916.modeset=1 to and vga=792 to the boot line.
I'm attaching dmesg and Xorg.0.log

It is too new, seems it was released after our kernel.
