Subject: qemu-emulated nfit devices disappeared

I've update my typical test configs last week without saving the old
ones, and now the Qemu emulated NFIT devices don't show anyway more
despite the kernel showing a NFIT table:

# mesg | grep -i nfit
[    0.009184] ACPI: NFIT 0x00000000BFFE02FA 000198 (v01 BOCHS BXPCNFIT 00000001 BXPC 00000001)
[    0.009206] ACPI: Reserving NFIT table memory at [mem 0xbffe02fa-0xbffe0491]

# lsblk 
NAME   MAJ:MIN RM  SIZE RO TYPE MOUNTPOINT
sda      8:0    0    8M  0 disk 
sr0     11:0    1 1024M  0 rom  
nullb0 250:0    0  250G  0 disk 
vda    252:0    0   10G  0 disk 
└─vda1 252:1    0   10G  0 part /

Any idea what might be missing in the attached config?  This seems to
be independent of the tested kernel version (5.14, 5.15, master).
