framebuffer size

[Emmanuel Dreyfus <manu%netbsd.org@localhost>]

Hello

I wonder if I can run X Window on a Dell Optiplex 5060. The graphic chip
is "UHD Graphics 630" (PCI vendor id 8086, product id 3e91).

I have not configured X11 for a while, but as I understand, accelerated
drivers now require kernel support though DRM, which is not done for
this chip, since I get a "drm at ... not configured" message:

genfb0 at pci0 dev 2 function 0: vendor 8086 product 3e91 (rev. 0x00)
genfb0: framebuffer at 0xc0000000, size 800x600, depth 32, stride 3200
wsdisplay0 at genfb0 kbdmux 1: console (default, vt100 emulation)
drm at genfb0 not configured

There is a suboptimal path using non acelerated, generic wsfb driver, just
like the vga and vesa driver in the old ages. That works and I can start
X11 with even a 32 bpp color depth. But the resolution is stuck to genfb0
size 800x600. Is there a way to improve that?  

Also, the machine has two displayport outputs. Is it possible to use
