>Description:
Trying out drmkms intel on a "desktop"

cpu0: "Intel(R) Atom(TM) CPU D525   @ 1.80GHz"
Vendor Name: Intel (0x8086)
Device Name: Pineview Integrated Graphics Device (0xa001)

which has a VGA and a DVI socket. The DVI socket is connected to a
monitor detected by another ivy bridge desktop as doing

intelfb0: framebuffer at 0xffff80008a8a1000, size 1680x1050, depth 32, stride 6720

but when connected to the pineview, only manages

intelfb0: framebuffer at 0xffff800024b7b000, size 1024x768, depth 32, stride 4096

xdm does work and terminal switching works.

(There is an oddity when using a serial console in that keypresses
don't make it into xdm's login screen - just like when you have a
getty running on the same screen as X - but logging into xdm works
fine with a consdev pc at the pxeboot prompt)
