xrandr shows 640x480 anx 1024x768 as the maximum.

Ah, yes I forgot to check the BIOS for this. In the BIOS there is an option
to twiddle the integrated vs NVIDIA card ("hybrid mode"). Now the i915
module states the following:
agp0: <Haswell mobile GT2 IG> on vgapci1
agp0: aperture size is 256M, detected 524284k stolen memory
info: [drm] Initialized drm 1.1.0 20060810
link_elf_obj_obj: symbol AcpiGetHandle undefined
linker_load_file: Unsupported file type
This I am only able to see when starting in "safe mode". Booting as normal,
the screen becomes black and I am unable to switch among the virtual
terminals. SSH also hangs or shows severe delays (maybe unrelated?).
I booted into the more verbose option in DF, and see the following when the
info: [drm] Supports vblank timestamp caching Rev 1 (10.10.2010).
info: [drm] Driver supports precise vblank timestamp query.
drm1: taking over the fictitious range 0xa0000000-0xb0000000
info: [drm] Initialized i915 1.6.0 20080730
info: [drm] Enabling RC6 states: RC6 off, RC6p off, RC6pp off
