....and I really wish my dedicated NVidia RTX 4070 Laptop GPU would be recognized with pciconf -lv so I can do gpu passthrough on it as on linux with virt-manager.
Lenovo Legion Pro 5 16IRX8

Are there any laptop this work on at all with FreeBSD?

I use AMD-powered Thinkpads with good success.

Are you sure your dgpu is turn on in the BIOS?

Yes its on.. Since i multiboot into windows, linux and freebsd. Only freebsd not finds it.
I know the thinkspads are a popular choice amongts bsd'er.. Only problem is i not found a thinkpad yet that has good enough GPU power that it makes sense to use it with GPU passtrough for gaming. Its something like 10 x slower in 3D in benchmarks

But the main purpose (for most) with passthrough virtualisation is to run other os (windows) without the need for restarting the machine and booting into another os. On limux i get it working playing windows games almost at full fps on the same laptop on separate screen and can drag the mouse cursor between the screens like a multi screen setup. Only with 2 OS's simultanious at almost no reduction in troughput.

Its just that BSD not yet are compatible with those motherboards in laptops yet with descrete graphics cards.

I guess BSD Foundation has it on theyre todo list. But I dont think they will have it ready for version 15

Just ran pkg upgrade on a VM running Alpha 2 and it's now alpha 3. ISO's are in snapshots on the ftp site.

I run current alphas too. Doing "pkg upgrade" once a week excited if my GPU will get recognized by pciconf -lv :) lol
Am still at alpha 2.. Maybe a upgrade will do it!!

I love that they went from freebsd-update to pkgconf approach.. Its closer to a "rolling" release now.. More like Arch Linux which is my favorite in linux world
 
Just upgraded to ALPHA 3.
Code: 
pciconf -lv | grep -B4 vga
    vendor     = 'Intel Corporation'
    device     = 'Raptor Lake PCI Express 5.0 Graphics Port (PEG010)'
    class      = bridge
    subclass   = PCI-PCI
vgapci0@pci0:0:2:0:    class=0x030000 rev=0x04 hdr=0x00 vendor=0x8086 device=0xa788 subvendor=0x17aa subdevice=0x3b5a

Still no good news for finding my dGPU :(

You might have better success with a laptop with a hardwired dGPU (can't switch between integrated GPU and dGPU).

Am not sure what you mean by hardwired dGPU.
As of my knowledge iGPU is what is called hardwired (integrated) and dGPU is dedicated GPU with its own chip and vram.
I have an Lenovo IdeaPad Gaming 3 also with iGPU (mix Radeon and Nvidia) and FreeBSD recognize both of them with pciconf -lv and it successfully loads both amdgpu and nvidia-modeset kernel modules with nvidia-drm-kmod from the official FreeBSD 15 Alpha 3 repository.
I haven't yet tried GPU passthrough on it, but I doubt it will work since iGPU share the same chipset. I will try it for fun with bhyve!

I think there is something about the BSD firmware for the motherboard that is not compatible with Lenovo Legion i5 motherboard.
