vesafb refuses mode 865 for dell XPS m1330

Binary package hint: linux-image

I quote from http://intr.overt.org/blog/?page_id=56:

For non-X console mode, I use the vesafb driver. Dell were nice enough to include the native 1280×800 mode in the vesa mode list, as mode 865 - so if you configure lilo or grub (depending on your preference) to pass that to the kernel at boot time, you’ll get a native mode console.

Ubuntu gutsy gibbon linux-image-2.6.22-14-generic virtual terminals break with this mode set. They show only a blinking cursor, no contents.
