the last generation of Intel Graphics Chips are not supported.
they are the successor of the i915 chips and can be found CoreDuo-Notebooks. They seem not to differ much from the last i915-PCI-Express chips, at least the official specs are the same.

dmesg lines concerning the device:
vga0: <Generic ISA VGA> at port 0x3c0-0x3df iomem 0xa0000-0xbffff on isa0

when hw.pci.allow_unsupported_io_range="1" is set, dmeag also shows:
pci0: <display, VGA> at device 2.0 (no driver attached)
pci0: <display> at device 2.1 (no driver attached)

pciconf -lv shows:
none0 at pci0:2:0: class=0x030000 card=0x01d81028 chip=0x27a28086 rev=0x03 hdr=0x00
    vendor   = 'Intel Corporation'
    class    = display
    subclass = VGA
none1 at pci0:2:1: class=0x038000 card=0x01d81028 chip=0x27a68086 rev=0x03 hdr=0x00
    vendor   = 'Intel Corporation'
    class    = display

vesa works, but widescreen resolutions set with 915resolution cant be used...
and of course DRI doesnt work. 

the chipset is supported fully on GNU/Linux with the regular intel driver and Xorg's i810.

there are quite a few notebooks and users affected by the problem, so i set priority to high. if that is inadequate please change it.

thanks for any help! ( this stretched resolution is terrible)
its a constant problem ;)
