i have asus 730 and asus 1030 silent cards both working for me
in my two main desktop systems now. the 730 did once assert(3)
in libdrm_nouveau and X exited, and the 1030 has one had some
minor display damage (green dots over the root window, likely
generated by my green-on-black terminal, but cleared by simply
moving a window over that space), and it's only been a couple
of weeks using the 730, and few days for 1030.
i don't have anything newer/better due to prices, and also cuz
the above are more than sufficient for my needs.
it's possible that back porting the rocket lake code wouldn't
be too difficult -- that was true a few years back when i did
this for kabylake when skylake was already supported... quick
peek says that RKL appeared right after our drm, sometime between
linux 5.6 and 5.10, and unfortunately, this struct:
static const struct intel_device_info rkl_info = {
in the new code has a couple of new members inside struct
intel_device_info{} than our code, so the back port would need
to consider these parts too.

No change with the gop command in UEFI mode. (I set a 1024x768 mode which was what DRMKMS seems to go for on my HW.) I only got a usable console in UEFI mode with this hack: https://mail-index.netbsd.org/tech-kern/2022/04/12/msg028065.html In CSM mode, the modesetting driver works OK except for minor glitches. But, if you try the `wsfb' Xorg driver on top of `intelfb' you get what I can only describe as a 1-line framebuffer (graphics mode). The same thing with a FB test program on the console. The framebuffer looks like a single line of 1024? pixels right at the top of the screen. And, compiling-in some fonts (notably SPLEEN12x24--anything which doesn't seem to be a multiple of 8x8) causes the kernel to reboot right at the start. Haven't had the time to hunt any of these snarks yet... -RVP

i can't easily check for a couple of weeks, but i have a system
i think i had to use UEFI for that had a 5450. it didn't fail
entirely like the above, it failed the "ring 3" test, and
disabled acceleration. this mean eg, X worked ok, but many things
use a lot of CPU. fortunately, this is a zen3 system so it's got
a lot of CPU -- would cost about 1.5 cpus to play a 1080p video.
this system has a nouveau 730 in it now, and everything is better
except one time libdrm_nouveau triggered an assert() and X crashed.
(an operation that should have a resource available didn't have it,
and the assert() tripped this wanted invariant. i don't have the
details handy.)
the 5450 is old enough that while pcie shouldn't have these sorts
of problems, i've had modern systems fail with pcie gpus, and i've
had newer gpus fail in older pcie systems -- i believe it was the
radeon RX 550 that caused my (old) core2 system to not boot.
do you have anything else handy to test? gpus are crazy stupid
prices these days :-(
