Anyhow, I'm up to the stage of configuring the kernel, and I'm stuck at
the bit where I need to specify the firmware to be incorporated into the kernel for the integrated graphics processor.

I'm running a Ryzen 5 3400G with Radeon Vega graphics:

That's a separate graphics card, isn't it? I'm trying to use the

$ lspci | grep -i vga

When I do lspci | grep -i vga, I just get:

VGA compatible controller, Advanced Micro Devices, Inc [AMD/ATI] Raphael (rev c4),

(well, something very similar, I'm copying it by hand). The "Raphael",
I believe, is the codename for the entire 7900 processor, not just the
graphics controller.

As I reported in another post, dmesg | grep firmware just gives me three

Yes, I get something like that on the installation system.

The codename was Raphael AM5, this uses a RDNA2 Raphael graphics as far as I can tell.

Perhaps you can try a different LiveUSB, e.g. Ubuntu to see if it provides
more info.

I'm running a Ryzen 5 3400G with Radeon Vega graphics:

That's a separate graphics card, isn't it? I'm trying to use the integrated graphics processor on my Ryzen 7900.

No, it's integrated into the Ryzen 5 3400G.

Sorry, I didn't recognise the chip number. Is it a laptop chip rather
than a desktop one?

Anyhow, in the last couple of days, I've managed to get my new system to
boot, and I'm currently busy trying to bring X and XFCE4 up. So I'm
getting there, slowly.
