Using SCFB or VESA on unsupported graphics device

I have a new laptop with Alder Lake graphics. While Linux now as the device
is listed as stable on the latest kernel, FreeBSD is not there, yet, and
probably won't be until it reaches a long-term support version. That leaves
me with  a nice paper weight.

I assume that I should be able to use SCFB or VESA toi et some graphics
support, but the attempt to start X results in a log entry that no graphic
device can be found. pciconf -lc reports:
gapci0@pci0:0:2:0: class=0x030000 rev=0x0c hdr=0x00 vendor=0x8086
device=0x4628 subvendor=0x17aa subdevice=0x22e8
    vendor     = 'Intel Corporation'
    device     = 'Alder Lake-UP3 GT2 [UHD Graphics]'
    class      = display
    subclass   = VGA

How do I make X recognise this device so that I can get graphics to work?

Thanks!
